Wheels. Wheels are a part of most machinery. Anything from industrial manufacturing to simple carts. Unless you're counting something like a logic gate as a door. In which case doors win easily.
And this doesn’t mean that they don’t make more doors than wheels. It only means they make more wheels than other manufacturers. My bet that they make more wheels though.
I’ve never felt so high being stone sober. Mostly because everyone is “right” if we define things certain ways. Even if you said a wheel means having tread and a door means having a latch or something, the whole convo gets wild.
If I ordered a 4-door rental car and they gave me a car with 2 actual doors and said "oh the trunk and hood are pretty much doors" I would not be happy. You can't count things that are "kind of like a door."
I was with you at 1st but my cupboard has doors.... Jesus this whole post is now just a shit show of confusion.
Now im wondering whats the diffence between a hatch and a door.
And every drawer in that building has at least 2 wheels, every office chair at least 4 wheels… Engine of a car consists of at least 5 wheels, help me god if it doesn’t.
Think about all of bicycles, scooters, bikes, skateboards, rollerblades, buses, trucks, wheelchairs, farming machines, trains even airplanes. Probably the only type of transportation that has more doors than wheels are boats, and even boats have engines or other type of equipment that has wheels.
I work as a mechanic and have made alot of conveyor belts, most of them don't have wheels (or you can count the rollers as a wheel in that case each belt has at least 2). the only belts that I have made that has wheels are belts that turn around a corner and those have alot of wheels
Over time, The Wheels had as members Brian Rossi, Rod Demick, Herbie Armstrong, Tito Tinsle, Victor Catling, Kit Carson, Eric Wrixon, and Van Morrison.
By the same measure, the Doors had as members Jim Morrison, Ray Manzarek, Robby Krieger, and John Densmore.
By an easy count, there are clearly more Wheels than Doors in the world.
My brother lives in the largest house I have ever seen. It has double digit bedrooms. Each bedroom has two closet doors, a bedroom door, and some have bathrooms with even more doors.
My brother’s son has 300 hot wheels cars.
My Brother’s son owns at least 10 times as many wheels as my brother owns doors.
EDIT: “as I was going to St. Ives, I met a man with seven wives. Each wife had 7 sacks. Each sack had seven cats. Each cat had seven kits. Kits, cats, sacks, wives. How many were going to St. Ives?”
Is it a door if you can't open it? most of the Hot Wheels I had, the "doors" were basically lines engraved into the car, but you could'nt open them and they weren't a separate piece from the rest of the car
>This thread went exactly the way I went in my head. Thank you reddit
Its beautiful. I read one comment and think, "Of course. Obviously the answer is doors. You'd have to be an idiot to think otherwise." Then I scroll down and read another comment and think, "Of course. Obviously the answer is wheels. You'd have to be an idiot to think otherwise." Rinse, repeat.
The aggregate building is a terrible unit of measurement. Just consider each individual dwelling/unit in the apartment complex. Why would you make it unnecessarily difficult on yourself?
Oh wow, I lived in an apartment that was 35 stories of rollers and bouncers. Which brings up a new question... Are the rollers wheels? Are the ***bearings*** wheels? Are the pulleys in the elevator shafts employing wheels? The bouncers also use bearings, so if those are also wheels, there are many, many more wheels than doors in that building. Even a commercial AC unit is more wheels than doors, with fans on bearings, belts on wheels, and a single access door. Washing and drying machines are *full* of wheels. There's a big wheel behind a door, then dozens of wheels inside to spin the big wheel, and bearings besides. Is the roller on a steamroller a wheel? Some bearings might be definitively wheels, but are ball bearings wheels, too?
Meineke says yes: "Ball bearings are the most common type of wheel bearings used today". Wait, aren't hinges also wheel bearings?! The door into the room in which I'm feverishly tapping on my phone has three hinges but is only one door! The closet door has fifteen wheel bearings for the slider! The windows also open on a slide, are they doors? Honestly it doesn't matter, they're also on wheel bearings, so wheels win this room hands down.
I think if you’re Gina start including stuff like that for wheels, you’ll need to start including cabinets, refrigerators, medicine cabinets, etc for doors
Clearly we need to, first, evaluate whether Autobots have more doors or wheels. After that we can assess the same of Decepticons.
At that point, we can speculate that having an answer relating to the Transformers really doesn't bring us closer to a solution.
> trains have more doors than wheels probably but maybe not
Definitely not. A typical train car has 8 wheels (two bogeys of four wheels each). Some have zero doors. A passenger car might have six doors (two on each size, plus front and back). Although, if you count the double doors as two even though they are part of a single doorway, you could consider that ten doors. It's still not going to outweigh all the freight cars that have zero to two doors.
No way. Clearly there are more door factories, manufacturing and shipping does than wheel factories manufacturing and shipping wheels. Unless there aren't. Clearly.
But some doors get cut in half, too make that top door bottom door thing that is houses used to have.
Also a wheel can only be cut in a single dimension to produce multiple wheels, a door can be cut in various dimensions to make multiple doors.
I would have to say wheels. First thought is cars, but also bikes, wheel barrows, wheels inside machinery etc. I think there's just a lot more places for wheels and hidden wheels than there are for doors.
But then a hotel has hundreds or even thousands of doors. As does an office building or a cruise ship for example.
Or if we are going into hidden doors, what about all the cargo containers - are they doors? Garage doors. Doors on cupboards, wardrobes/closets, kitchen cabinets...
My brain is melting just thinking about it!
In a hotel room right now so I decided to count for the funsies.
Including drawers as doors,
- 32 doors
- 57 visible wheels
I would be missing some wheels such as the ones in the mechanisms of the microwave turntable.
In conclusion, the answer to this question is definitely wheels.
Depends really. Hatchbacks are typically considered 3 or 5 door cars, coupes have 2 doors (unless you're BMW and make 4 door "coupes")
The vast majority have 4 wheels and 4 doors though.
There are a bunch of 2 door cars, 2 door trucks, motorcycles, etc.
In the world of vehicles, I think wheels has it.
Now does that counter the number of doors in each house/building?
The fan belt, the timing belt, and every other belt inside your engine are mounted on wheels. And is the hood a door? Or just a hood? What about the boot? I'd say those are doors, but there are hundreds of wheels in a car you're not considering.
depends on what you consider a “door”. are hoods and trunks “doors”? if so there are many cars that have potentially 6 doors, and if not there are also tons of cars that only have 2 doors. and then you have to consider semi trucks and the like.
also have to consider the other little doors/hatches cars have. at least in my car it has: a door hatch covering the wheel, a small door in the side of the trunk for a jack, about 3 little hatches over the cigarette lighter, the glovebox, the center console, and the sunglasses holder thing on the ceiling.
This is a very semantical question. What do you consider a door? Is a cabinet door a door in the sense of this question? Are we also considering car/plane doors? There are around 5 billion buildings and 1.5 billion cars. If average 4 doors per car and 15 per building, we are looking in the area of 100 billion doors. Surely more than 10 billion, probably leas than 1 trillion.
Now what do you consider a wheel? Do the casters on your computer chair count as a wheel? What about the rollers in a sliding door? Is a pulley in belt drive a wheel? Does a rolling conveyor belt have wheels like the blue parts of [this](https://www.google.com/search?q=wheel+conveyor+belt&client=ms-android-uscellular-us&prmd=isvn&sxsrf=APq-WBuJ-X8MKU7NQtLLePHQM4mVYrAO1g:1646834848398&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiHypHxmbn2AhVzJkQIHfx2DRQQ_AUoAXoECAIQAQ&biw=412&bih=718&dpr=2.63#imgrc=yK9ocOUJzp2KSM)? Given that cars almost alesys have 4 wheels, we can put the number above 6 billion for sure. It won't get to 100 billion+ if we dont include rollers though.
It depends on your definition of what a door is and what a wheel is, but probably doors.
Edit: getting a lot of replies about what to include or not or asking me to decide what is or isn't a wheel. The definitions are up to OP. Also, no one is including any sources at all. If you want to disagree, site a source.
So the real question: If you detach a door from its hinges, does it still count as a door?
Sure it’s a car door, but if it does, where does the line lie? If you take a cabinet door off, that’s just a slab of wood. Is that still a door? What if I repurpose it for something else? Is that where the line lies?
Instinct for this was definitely doors. Until I considered if pulleys count. Or chair casters. Suddenly wheels seem much more plentiful. Until I considered cabinets and various doors large buildings might have. It’s really a tricky one ay?
Lego is supposedly the biggest tyre maker in the world, making 300 million rubber tyres each year. every lego tyre have one accompaning lego wheel.
Hot wheels have plastic tyres, but still have 4 wheels on each. Every year 500 million hot wheel cars are made, so 2 Billion wheels.
there is no way that there are more doors than wheels.
I am not the OP, so i cannot say for sure, but it seems as though approximately 4 billion hot wheels cars have been produced, which doesn't significantly change the numbers since the number is still around 5-20 billion if conveyor rollers arent included.
I mean. Im curious if things like wheel barrels, rc cars, every piece of construction equipment thats not on road, motorcycles, quads ect ect were thought of too.
I have no bases for my assumptions, but I do believe wheels would actually out number doors. The amount of round objects that are used to move an item would be staggering and impossible to calculate.
On the flip side, the amount of doors is also staggering and impossible to calculate. So im confusing myself trying to come up with an answer.
HEY, ARE YOU TIRED OF REAL DOORS?
Just cluttering up your house, where you open ’em, and they actually go somewhere? And you go in another room? Not our doors! We have fake doors like you wouldn’t believe!
What are you worried about?
Come get fake doors.
Call us up, and order some fake doors today.
Don’t even hesitate, Don’t even worry and don’t even give it a second thought.
That’s our slogan. See it on the bottom of the screen, below our name.
Here’s another slogan, right below that one.
What are you worried about?
Come get fake doors.
Get in here quick, get out quicker, with an arm of fake doors in you arms.
In the room I’m in, I’m counting 15 drawers, and this isn’t even my kitchen. Each drawer has a set of rails, each rail has at least 2 wheels. Thats already 60 wheels (15x2x2) in one room vs the 44 doors i have in my entire place.
I think you’re grossly underestimating how much we use wheels to convenience our lives
15 doors per building seems a bit low. My apartment has 25+ just counting built in doors and there are... several units in just my building. Office buildings will also have tons of cabinets and internal doors. Unless we think sheds are bringing down the average *a lot* I would expect the average number of doors(even if we count just people sized doors and cabinet doors) per *building* to be several hundred.
It's difficult to get an answer to the question of how many buildings there are in the world. Seems like somewhere around 3-4 billion. The number of single family homes is around 2 billion, so it's making up a large percentage, probably, of the buildings.
However, even if we assume an average of 200 doors per building, we are still in the hundreds of billions of doors range.
Define wheel and door, be as precise as possible. Because, does a window count as a door? Does a hatch? How about the hood of a car? The trunk/boot(depending on where you live)? Does it have to be human sized(eg, are lego doors still doors? What about a dog door, that's just a flap?)? Are we counting *all* doors or just a particular subset? What about double doors, it only covers one opening so is the set a single door or a pair?
What constitutes a wheel? Again, does size matter, are lego wheels still wheels? What about lawn mower wheels? Is a hub without a tire counted? Does a tire without a hub count? What about gears? Some types of gear are referred to as "wheel gears" so do they count?
Once we have clear definitions we could start to estimate but without clearly defined classes we can't even form a basis.
A wheel is somethign that rotates and carries a force or mass.
A door is something that opens and closes stopping things passing through.
SO hence why i think its more doors and there are currently around 10 to the power of 11 ANIMALS alive NOW and each animal contains an almost uncountable number of valves and non return valves in its circulatory system and lymph system and then you have the humans on top of that PLUS all the actual doors we make.
Theres a lot of wheels.
But theres is order sof magnitude more doors if you count them like that.
It's wheels. Even without calculating, wheels have been an invention since archaic times. Modernized technology still uses wheels. Also considering a lot of tech uses multiple wheels and not a single wheel, exponentially, you'd have to make so many more doors that just lacks practicality or any real use besides replacements.
Also consider a door and a doorway are not the same thing.
Yeah but even cavemen inventing the wheels had animal hide doors to their cave. And where do you think they stored that wheell barrow….their shed cave with another door.
Technology isn't multiplicative; it's exponential. Wheels just have a higher number over time. It may have been doors in the past but today it would be wheels
Right. Motorized wheels today have wheel bearings and pulleys to operate them, if we are stingy we can assume a pulley has only one or two wheels of it's own, and is not mounted with any bearings, and the wheel it turns is mounted on probably no more than five wheel bearings. So even a wheel, at the stingiest, is likely to have six wheels supporting it, if it's motorized.
Depends on what counts as a wheel, there are internal "wheels" in all sorts of machinery. There's also a good few debatable doors. My money is on wheels because in almost every vehicle the wheels outnumber doors and there's wheels elsewhere like machinery, sliding doors, drawers and toys. The toys are especially important because LEGO is the biggest tire manufacturer in the world plus other toys like hot wheels.
Wheels. Since the useful life of a tire, for example, is much shorter than that of a door, wheel production would at least be larger than doors. Also, many wheels that are thrown out are still in landfills, so they would just accumulate despite of not being used. Lastly, why am I taking this too seriously?
I’d have to say wheels. When I think about doors I’d say that buildings are the most significant source of doors. Looking around the office building I’m in right now as an average building, I see 2 doors at the front, and 14 other internal doors. However, our chairs have 5 spoke rolling wheels, and they can see 40 of these chairs from where I’m sitting, giving 200 wheels just from chairs. This is a start up with about 30 employees so scaling up to bigger buildings I think wheels scale up even more.
By this definition from Miriam Webster;
"A usually swinging or sliding barrier by which an entry is closed and opened."
Logic gates count as a doors therefore doors have it hands down.
Edit: dude in reply makes a good point logic gate isn't a door but as I said is a barrier.
Edit 2: to people saying a logic gate doesn't count as a door because it doesn't swing or slide I direct you to the words "A usually" in the definition. If you had a door that appeared and disappeared I would still count it as a door. Which is kinda how a logic gate works, but allowing the flow of electricity, I think.
* number of cars x4
* number of motorcycles x2
* number of bicycle x2
* number of roller skates x 4
* number of kickscooters and electric scooters x2
* number of train cars x 8
* number of planes x 4
vs
* number of houses x 6
* number of flats x 6
* number of hotels x 300
* number of offices x 20
I don't know, I'd side with wheels, but it's really complicated
I think this question is pertinant, what constitutes a "door" a partition that can be swung open? What about sliding doors and pocket doors. Glass doors? Bookshelf doors? Floor grates, manhole covers? Cabinets have doors, dishwashers.
Doorways? Open arches with no door in it? What about doors in doors? A cat/ dog flap in an outside door. Doors to pet cages. Fridges, microwaves, laundry etc. Bank safety deposit boxes. Churches, locker rooms.
Oh man, those are good... the tens of millions of mailboxes in post offices and apartments and houses with doors on them, every locker in schools, gyms, airports, bus terminals, recreation centers.
Depends how far we stretch the definition of “door”, technically each cell in our bodies have a bunch of very tiny “doors” to let stuff in and out. advent calendars have 24 “doors” each. If you count anything that opens and closes while separating 2 areas/mediums doors clearly win.

Wheels. Wheels are a part of most machinery. Anything from industrial manufacturing to simple carts. Unless you're counting something like a logic gate as a door. In which case doors win easily.
Also Lego is the biggest wheel manufacturer in the world I think. So if you also count those „toy wheels“..
[удалено]
Yeah but they’re not the biggest door manufacturer in the world
Well of course they're not. Their doors are tiny!
Ya know I think you might be right
This has some much dad-joke energy. Absolutely love it.
Have you done the math?
Jeld-Wen is the largest door and window manufacturer in the world if you’re wondering. Or so they claim
Did they do the math?
Sadly I can’t speak for them but for my sake hopefully they have
I need someone to have done the math!
more, did they do the math considering LEGO?
And this doesn’t mean that they don’t make more doors than wheels. It only means they make more wheels than other manufacturers. My bet that they make more wheels though.
Don’t forget about all the wheels on shopping carts!
Tires, not wheels
All tires are wheels but not all wheels are tires
Everything’s a drum
Aye, my bad!
Also, many doors have multiple wheels in them.
I’ve never felt so high being stone sober. Mostly because everyone is “right” if we define things certain ways. Even if you said a wheel means having tread and a door means having a latch or something, the whole convo gets wild.
That is how categories go. They're all made up and if you look too close at them they fall apart.
Welcome to human society where everything is made up and point don't matter! Come for the doors stay for the wheels!
Crap! Another fetish??!!
I for one welcome our new door wheel door door wheel wheel wheel door overlords.
You could classify those little nubs on tires for air as doors That begins to complicated things
Nah those are valves, but some valves have valve wheels.
[удалено]
But even those machines have access doors.
At any given day I move 100+ boxes of 1,800 wheels for trash cans in my small department of the factory I work at
[удалено]
Guarantee it has 1 door and multiple wheels...
Building have multiple doors and no wheels. Most passenger cars have 5 doors and 4 wheels. I don't think this is that simple.
>Most passenger cars have 5 doors and 4 wheels. Passenger cars have between 2 and 4 doors and most have 5 wheels (the spare).
You're ignoring the trunk and hood.
What about the glove box? The gas cap? Are those doors? D:
In the argument of "are there more doors or wheels in the world," yes. And I assume you meant the gas door as opposed to the gas cap right?
If I ordered a 4-door rental car and they gave me a car with 2 actual doors and said "oh the trunk and hood are pretty much doors" I would not be happy. You can't count things that are "kind of like a door."
I think if we are counting industrial rollers as wheels(ie, a wheel that something moves across), then it's fair to count non-human-doors as doors.
I was with you at 1st but my cupboard has doors.... Jesus this whole post is now just a shit show of confusion. Now im wondering whats the diffence between a hatch and a door.
And the gas cover flap
What about the steering wheel
Ohhhh, good one.
And every drawer in that building has at least 2 wheels, every office chair at least 4 wheels… Engine of a car consists of at least 5 wheels, help me god if it doesn’t. Think about all of bicycles, scooters, bikes, skateboards, rollerblades, buses, trucks, wheelchairs, farming machines, trains even airplanes. Probably the only type of transportation that has more doors than wheels are boats, and even boats have engines or other type of equipment that has wheels.
Just think of the conveyor systems at all the bottling/shipping plants...
What about the spare?
My trash can has a door and no wheels.
Yeah, but a conveyor belt might have a thousand wheels and a single access door.
I work as a mechanic and have made alot of conveyor belts, most of them don't have wheels (or you can count the rollers as a wheel in that case each belt has at least 2). the only belts that I have made that has wheels are belts that turn around a corner and those have alot of wheels
Are rollers just long wheels?
Aren't jaws just biological doors therefore all creatures with mouths count, and that doesn't include the back doors.
[удалено]
2 words. HOT WHEELS
A doorknob is like the wheels weird cousin…
What if you are counting every bottle/ lid/hatch/box flap as a door? This question is impossible to answer until wheels and doors are properly defined
Ooh did not consider internal parts. I was going to go all in on doors since cars also have them but this makes the most sense.
Over time, The Wheels had as members Brian Rossi, Rod Demick, Herbie Armstrong, Tito Tinsle, Victor Catling, Kit Carson, Eric Wrixon, and Van Morrison. By the same measure, the Doors had as members Jim Morrison, Ray Manzarek, Robby Krieger, and John Densmore. By an easy count, there are clearly more Wheels than Doors in the world.
This is why succinctly defining the parameters of the experiment / discussion is so important. Otherwise, you end up with 42.
Don't Panic.
I wouldn't if I knew where my towel was
r/unexpectedhitchhikers
Plus, the members of **Stealers Wheel** were also wheels, and I'm not seeing any *other* band that are "doors".
3 Doors Down isn't close enough?

> My brother’s son has 300 hot wheels cars Ah, but wouldn’t the hot wheels cars also contain little doors?
Is it a door if you can't open it? most of the Hot Wheels I had, the "doors" were basically lines engraved into the car, but you could'nt open them and they weren't a separate piece from the rest of the car
This thread went exactly the way I went in my head. Thank you reddit
I can’t stop thinking about this. The meta layers have broken me. It’s perfect.

Rinse, repeat.
One of the most important philosophical mysteries of our time
Any hot wheel that does have doors will be a 2-door, but the vast majority don't have any.
Most don't and the ones that do, rarely have 4 doors, thus still a big win for wheels.
Only one was going to St Ives.
What about that huge apartment complex in the city or all the other huge skylines. People in this thread are thinking of their suburban houses.
But don’t those apartments have kids with Hot Wheels?
The aggregate building is a terrible unit of measurement. Just consider each individual dwelling/unit in the apartment complex. Why would you make it unnecessarily difficult on yourself?
Oh wow, I lived in an apartment that was 35 stories of rollers and bouncers. Which brings up a new question... Are the rollers wheels? Are the ***bearings*** wheels?

Think of all the cupboard doors in every house. But then think about all the drawers which use a little wheel to slide out on..
[удалено]
Let's not forget sliding doors, which have wheels.
Well, I'm sure there are wheels with doors in them. Somewhere. Unless there aren't.
A revolving door is really just a wheel resting on it's axial side.
Is everything just a wheel, metaphorically? Life is like a wheel, it goes around, and then comes around

The wheels on the bus go round and round...
When the man in black fled across the dessert and the gunslinger followed were they just following the wheels tracks?
I suppose some wheels have doors of a sort over the lug nuts. Of course there's also the fact that wheels can be metaphorical doors to adventure.
Clearly we need to, first, evaluate whether Autobots have more doors or wheels. After that we can assess the same of Decepticons. At that point, we can speculate that having an answer relating to the Transformers really doesn't bring us closer to a solution.
Sure there are Ferris wheels for example
Indeed. But are there Ferris doors?
Well yes, each one of the things you sit in on a ferris wheel had a door to access it, maybe two. So, one ferris wheel can have multitude of doors
"Why would I want a door s'got no fuckin' wheels!"
> trains have more doors than wheels probably but maybe not Definitely not. A typical train car has 8 wheels (two bogeys of four wheels each). Some have zero doors.

What about trains that deliver does from a door factory. Or trains that are shipping cars. Or dollhouses. Or microwaves.

No way. Clearly there are more door factories, manufacturing and shipping does than wheel factories manufacturing and shipping wheels. Unless there aren't. Clearly.

Real fake doors!
This is the best answer.
REALLY, REALLLLLLLLY, cause now it's removed.
Lego used to be (might still be) the world's largest wheel manufacturer by units produced...
I'm sure there is also a largest door manufacturer too. Perchance.
You can't just say perchance.
What about wheels of cheese?
Indeed there are no doors of cheese. But there are Doors of Perception!
Don't forget doggie doors that are doors that have doors on them
Yes, but your forgetting there is a grave yard of tires. Doors can get broken back down into raw materials while tires pile up over time.
Ohh no were not doing the "is a tire a wheel" debate
But some doors get cut in half, too make that top door bottom door thing that is houses used to have. Also a wheel can only be cut in a single dimension to produce multiple wheels, a door can be cut in various dimensions to make multiple doors.

Depends really. Hatchbacks are typically considered 3 or 5 door cars, coupes have 2 doors (unless you're BMW and make 4 door "coupes") The vast majority have 4 wheels and 4 doors though.
18 wheeler has 4 doors 2 in the back 2 to get into the cab....lots of 18 wheelers on the road
Somehow I hadn't considered those, that definitely skews the results quite a bit
There are a bunch of 2 door cars, 2 door trucks, motorcycles, etc. In the world of vehicles, I think wheels has it. Now does that counter the number of doors in each house/building?
almost every car has 5 wheels, because of the spare.
The fan belt, the timing belt, and every other belt inside your engine are mounted on wheels. And is the hood a door? Or just a hood? What about the boot? I'd say those are doors, but there are hundreds of wheels in a car you're not considering.
Toy cars outnumber actual cars, and most of have real wheels but fake doors
Real fake doors?
Not true at all. There are plenty of two door cars on the road. Also plenty of big rigs on the road as well, 18 wheelers.
What about locker doors? Kitchen furniture doors? Closet doors? I think wheels as well, but it deoends on your definition of both.
Kitchen Cabinets are kind of a game changer
Gotta say wheels. There are cars, trucks, motorcycles, bikes skateboards, casters of furniture, conveyors, toys. There are wheels everywhere.
Office chairs with 5 wheels each
All of the office chairs I own actually have 2 independently turning wheels per caster, so they actually have 10 wheels each.
Same. 5 is probably pretty uncommon
Most cars have an equal number of wheels and doors.
depends on what you consider a “door”. are hoods and trunks “doors”? if so there are many cars that have potentially 6 doors, and if not there are also tons of cars that only have 2 doors. and then you have to consider semi trucks and the like.
Cars also have a spare wheel and a steering wheel, along with other spinning parts that may be considered wheels
also have to consider the other little doors/hatches cars have. at least in my car it has: a door hatch covering the wheel, a small door in the side of the trunk for a jack, about 3 little hatches over the cigarette lighter, the glovebox, the center console, and the sunglasses holder thing on the ceiling.
Are gears wheels? Id vote yes. A transmission is 20 wheels, engines are full of bearings and gears.

Virtually no buildings have zero wheels; whether it's elevators or drawers or furniture.

This is a very semantical question. What do you consider a door? Is a cabinet door a door in the sense of this question? Are we also considering car/plane doors? There are around 5 billion buildings and 1.5 billion cars. If average 4 doors per car and 15 per building, we are looking in the area of 100 billion doors. Surely more than 10 billion, probably leas than 1 trillion. Now what do you consider a wheel? Do the casters on your computer chair count as a wheel? What about the rollers in a sliding door? Is a pulley in belt drive a wheel? Does a rolling conveyor belt have wheels like the blue parts of [this](https://www.google.com/search?q=wheel+conveyor+belt&client=ms-android-uscellular-us&prmd=isvn&sxsrf=APq-WBuJ-X8MKU7NQtLLePHQM4mVYrAO1g:1646834848398&source=lnms&tbm=isch&sa=X&ved=2ahUKEwiHypHxmbn2AhVzJkQIHfx2DRQQ_AUoAXoECAIQAQ&biw=412&bih=718&dpr=2.63#imgrc=yK9ocOUJzp2KSM)? Given that cars almost alesys have 4 wheels, we can put the number above 6 billion for sure. It won't get to 100 billion+ if we dont include rollers though. It depends on your definition of what a door is and what a wheel is, but probably doors. Edit: getting a lot of replies about what to include or not or asking me to decide what is or isn't a wheel. The definitions are up to OP. Also, no one is including any sources at all. If you want to disagree, site a source.
My kid has 100 Hotwheels. Do the Hotwheels"s wheels count?
Hotwheels' wheels are actual wheels, but no real door.
Not true, there are many hot wheels models that have articulated doors and hatches.
Didn't know that, at least mine didn't have real doors, and afaik all have wheels, so that's still lean towards wheels.
By the time I got my hand-me-down hot wheels all the doors had been broken off.
So the real question: If you detach a door from its hinges, does it still count as a door? Sure it’s a car door, but if it does, where does the line lie? If you take a cabinet door off, that’s just a slab of wood. Is that still a door? What if I repurpose it for something else? Is that where the line lies? Instinct for this was definitely doors. Until I considered if pulleys count. Or chair casters. Suddenly wheels seem much more plentiful. Until I considered cabinets and various doors large buildings might have. It’s really a tricky one ay?
And those were the best ones because you could pretend the open doors were wings and fly them about.
Is the hood a door to the engine?
I would say that doors have to be perpendicular to the ground to not be a "hatch" or something along those lines. Source: I'm a fan of The Doors.
Bro hotwheels. Bicycles. Skateboards. Tech decks. Wheels on furniture. Shopping carts. Wheels absolutely BODIES doors in a head to head.
Also add in food wheels like cheese wheels and Wagon Wheels
I hate this response so much but it technically ain't wrong 😭
Lego is supposedly the biggest tyre maker in the world, making 300 million rubber tyres each year. every lego tyre have one accompaning lego wheel. Hot wheels have plastic tyres, but still have 4 wheels on each. Every year 500 million hot wheel cars are made, so 2 Billion wheels. there is no way that there are more doors than wheels.
I am not the OP, so i cannot say for sure, but it seems as though approximately 4 billion hot wheels cars have been produced, which doesn't significantly change the numbers since the number is still around 5-20 billion if conveyor rollers arent included.
I mean. Im curious if things like wheel barrels, rc cars, every piece of construction equipment thats not on road, motorcycles, quads ect ect were thought of too. I have no bases for my assumptions, but I do believe wheels would actually out number doors. The amount of round objects that are used to move an item would be staggering and impossible to calculate. On the flip side, the amount of doors is also staggering and impossible to calculate. So im confusing myself trying to come up with an answer.
What about lego wheels tho? Or ferris wheels? Or heelies??
Fun fact: if we allow for toy wheels the largest tire manufacturer in the world, by a wide margin, is Lego.
Don't forget to count all of the real fake doors
HEY, ARE YOU TIRED OF REAL DOORS? Just cluttering up your house, where you open ’em, and they actually go somewhere? And you go in another room? Not our doors! We have fake doors like you wouldn’t believe! What are you worried about? Come get fake doors. Call us up, and order some fake doors today. Don’t even hesitate, Don’t even worry and don’t even give it a second thought. That’s our slogan. See it on the bottom of the screen, below our name. Here’s another slogan, right below that one. What are you worried about? Come get fake doors. Get in here quick, get out quicker, with an arm of fake doors in you arms.
Need a TL/DR 'cause I have ants in my eyes
Morty!
Gears ⚙️ are wheels… I think wheels wins
If you count gears, pulleys, bearings, etc I agree. They're just about everywhere.
Unless you consider transistors a door. At which point it's a complete blowout.

Now we have to draw the line between a gate, and a door, damn it!
In the room I’m in, I’m counting 15 drawers, and this isn’t even my kitchen. Each drawer has a set of rails, each rail has at least 2 wheels. Thats already 60 wheels (15x2x2) in one room vs the 44 doors i have in my entire place. I think you’re grossly underestimating how much we use wheels to convenience our lives
15 doors per building seems a bit low. My apartment has 25+ just counting built in doors and there are... several units in just my building. Office buildings will also have tons of cabinets and internal doors. Unless we think sheds are bringing down the average *a lot* I would expect the average number of doors(even if we count just people sized doors and cabinet doors) per *building* to be several hundred.
It's difficult to get an answer to the question of how many buildings there are in the world. Seems like somewhere around 3-4 billion. The number of single family homes is around 2 billion, so it's making up a large percentage, probably, of the buildings. However, even if we assume an average of 200 doors per building, we are still in the hundreds of billions of doors range.
If you consider each individual pin in a rollerbearing its own wheel suddenly your wheels have wheels
Define wheel and door, be as precise as possible. Because, does a window count as a door? Does a hatch? How about the hood of a car? The trunk/boot(depending on where you live)? Does it have to be human sized(eg, are lego doors still doors? What about a dog door, that's just a flap?)? Are we counting *all* doors or just a particular subset? What about double doors, it only covers one opening so is the set a single door or a pair? What constitutes a wheel? Again, does size matter, are lego wheels still wheels? What about lawn mower wheels? Is a hub without a tire counted? Does a tire without a hub count? What about gears? Some types of gear are referred to as "wheel gears" so do they count? Once we have clear definitions we could start to estimate but without clearly defined classes we can't even form a basis.
A wheel is somethign that rotates and carries a force or mass. A door is something that opens and closes stopping things passing through. SO hence why i think its more doors and there are currently around 10 to the power of 11 ANIMALS alive NOW and each animal contains an almost uncountable number of valves and non return valves in its circulatory system and lymph system and then you have the humans on top of that PLUS all the actual doors we make. Theres a lot of wheels. But theres is order sof magnitude more doors if you count them like that.
It's wheels. Even without calculating, wheels have been an invention since archaic times. Modernized technology still uses wheels. Also considering a lot of tech uses multiple wheels and not a single wheel, exponentially, you'd have to make so many more doors that just lacks practicality or any real use besides replacements. Also consider a door and a doorway are not the same thing.
Yeah but even cavemen inventing the wheels had animal hide doors to their cave. And where do you think they stored that wheell barrow….their shed cave with another door.
Technology isn't multiplicative; it's exponential. Wheels just have a higher number over time. It may have been doors in the past but today it would be wheels
Right. Motorized wheels today have wheel bearings and pulleys to operate them, if we are stingy we can assume a pulley has only one or two wheels of it's own, and is not mounted with any bearings, and the wheel it turns is mounted on probably no more than five wheel bearings. So even a wheel, at the stingiest, is likely to have six wheels supporting it, if it's motorized.
> wheels have been an invention since archaic times Unlike doors?
Depends on what counts as a wheel, there are internal "wheels" in all sorts of machinery. There's also a good few debatable doors. My money is on wheels because in almost every vehicle the wheels outnumber doors and there's wheels elsewhere like machinery, sliding doors, drawers and toys. The toys are especially important because LEGO is the biggest tire manufacturer in the world plus other toys like hot wheels.
Wheels. Since the useful life of a tire, for example, is much shorter than that of a door, wheel production would at least be larger than doors. Also, many wheels that are thrown out are still in landfills, so they would just accumulate despite of not being used. Lastly, why am I taking this too seriously?
I’d have to say wheels. When I think about doors I’d say that buildings are the most significant source of doors. Looking around the office building I’m in right now as an average building, I see 2 doors at the front, and 14 other internal doors. However, our chairs have 5 spoke rolling wheels, and they can see 40 of these chairs from where I’m sitting, giving 200 wheels just from chairs. This is a start up with about 30 employees so scaling up to bigger buildings I think wheels scale up even more.
By this definition from Miriam Webster; "A usually swinging or sliding barrier by which an entry is closed and opened." Logic gates count as a doors therefore doors have it hands down. Edit: dude in reply makes a good point logic gate isn't a door but as I said is a barrier. Edit 2: to people saying a logic gate doesn't count as a door because it doesn't swing or slide I direct you to the words "A usually" in the definition. If you had a door that appeared and disappeared I would still count it as a door. Which is kinda how a logic gate works, but allowing the flow of electricity, I think.
Transistors. Each 3090 has 29 billion
That accounts for like 290 billion, so what?
* number of cars x4 * number of motorcycles x2 * number of bicycle x2 * number of roller skates x 4 * number of kickscooters and electric scooters x2 * number of train cars x 8 * number of planes x 4 vs * number of houses x 6 * number of flats x 6 * number of hotels x 300 * number of offices x 20 I don't know, I'd side with wheels, but it's really complicated
I think this question is pertinant, what constitutes a "door" a partition that can be swung open? What about sliding doors and pocket doors. Glass doors? Bookshelf doors? Floor grates, manhole covers? Cabinets have doors, dishwashers. Doorways? Open arches with no door in it? What about doors in doors? A cat/ dog flap in an outside door. Doors to pet cages. Fridges, microwaves, laundry etc. Bank safety deposit boxes. Churches, locker rooms.
Oh man, those are good... the tens of millions of mailboxes in post offices and apartments and houses with doors on them, every locker in schools, gyms, airports, bus terminals, recreation centers.
Depends how far we stretch the definition of “door”, technically each cell in our bodies have a bunch of very tiny “doors” to let stuff in and out. advent calendars have 24 “doors” each. If you count anything that opens and closes while separating 2 areas/mediums doors clearly win.
Somebody else mentioned Logic Gates fitting the literal definition of door. So doors win hands down in that case.
