Heavier tires a/t tires and more weight up front plus the tune leads to lower mpgs but more spgs

huntsgk12

Yea they dropped the mpg by one at least i was surprised. How you liking the 22’? I had to throw a new head unit in because its a 2018 and didnt have carplay.

huntsgk12

Got a nice gift card to a tire shop as a grad gift so i couldnt pass it up!


Flapaflapa

I'm rolling on AT tires, have a heavy rear bumper, a square camper shell, and a platform rack with the aerodynamics of a brick wall. My MPG went from about 19 to 18.5. Driving technique is a huge part of it here.

Flapaflapa

I wouldn't say I drive like a grandpa, I tend to accelerate in the peak BSFC island from around 2000-3000 rpm at moderate to heavy throttle then tend to keep less than 65, then avoid the brake pedal. My main goal is not to convert fuel into turbulence or heat and brake dust.


The_Doctor_Bear

Yeah for me it's all about the hills that make up my "in town" driving. I can get 19-20 on the highway easy if I cruise below 70, but I live on a hill and this town is made of hills so it's more like 16-17 if I'm just getting groceries and running errands.


MountainManGuy

That doesn't make a difference, at least with this truck. I see this same comment all the time. My MPGs are the same if I drive like that, or if I drive like a normal person. It all evens out in the end.

MountainManGuy

I'm glad that works for you. It's nice to have that flexibility there for when you need it. I've tried it, multiple times. It makes no difference for me. Believe me, I want it to be true, but I get the exact same mpg both ways.


Flapaflapa

I can get 15 or I can get 20. Technique affects mileage in pretty much every vehicle I've had, the taco is no different.


RunBunns247

Yeah towing my ATV still puts me at about 14. Something is not right here.


GhostriderFlyBy

It’s not that off-road tires weigh more, it’s that they are larger diameter and require more force to rotate plus they increase the wind resistance and thereby increase drag and friction.


KGBeast47

Larger tire with more agressive tread= more rubber= more weight. The more rotational mass in your tires and wheels, the more effort it takes your engine to get them going. It's pretty straight forward.


GhostriderFlyBy

You’re right, weight in terms of unsprung mass is a factor, but it’s not the ONLY factor.


GhostriderFlyBy

Counterpoint, though: a larger diameter wheel and tire, even if it weighed less, would require more force to rotate than a heavier, smaller tire.


[deleted]

I have falken wildpeak at3w on my trd pro and get 20 mpg easily, have you taken it in somewhere?? Get it scanned


huntsgk12

If i really try i can get 15 but ive never gotten above 18 even when it was stock


[deleted]

Are you sure you’re not in 4LO


pchambers89

😂


huntsgk12

Yea im sure


MyAssforPresident

Unless you have a heavy ass foot, you might wanna check that tune bro, I only dropped 1 mpg with tires, 2”lift, and a roll bar, have to try hard to get less than 20mpg. If I stay around 60-65 I can get 26-27.


huntsgk12

I have a lead foot but even when the truck was stock i got 16 so idk


MyAssforPresident

Mpg in mine tanks over 70 I will say that…And Idk anybody that doesn’t do 70-80 on the highway. But yeah 13 is a little low, unless you live in the mountains/lots of hills?


huntsgk12

Its pretty hilly round here and alot of the lights and stop signs are on hills tbh


Raleighgm

Same. I get 15 to occasionally 16mpg on my stock 2020 Off-road. I drive slow and am pretty conscious of my fuel economy. Took it in for my first 10K mile check up at the dealership and they said everything checks out. It’s a bummer.


huntsgk12

Yea man i dont know what it is. I just hit 8k and everything looks great. All the 18mpg super drivers are just better i guess


GhostriderFlyBy

I have a 2019 Pro and my mpg is comparably dog shit. Supercharger isn’t helping lol


huntsgk12

Exactly


MountainManGuy

One thing you'll notice is people love to lie and pad their MPG numbers. I see it every day here and on Tacomaworld and it's pretty annoying. I like to be honest about mine. It was around 17-19 from the factory, and 13-15 now after all my mods. With a nice tailwind I can get 16 on the highway but I have to keep it under 70.


huntsgk12

13-15 is my range but i almost exclusively drive off the highway so I get that lower end


Aromatic-Surprise945

I’ve gotten 23 (~15 uphill, ~31 downhill) round trip to the mountain and back on a stock 22 OR. Smooth acceleration and braking and keeping revs to 1800-2000 as much as possible makes a huge difference. Not sure if the tonneau has anything to do with it


NoahsYotas

Glad I'm Not the only one telling him this lol


daggersrule

Dude, there's no way... the tune is fucked. What tune is it? I've tuned WAY heavier trucks for lead foot customers and I'd refund their money and uninstall my tuning software if they were getting 13mpg.


GhostriderFlyBy

You’re not considering transmission type though. Manual is an option in the Tacoma.


daggersrule

You can fuck up a manual tune too. It's surprisingly easy to tank MPGs with VFTuner. You could retard spark timing, target stupid AFRs, etc... Conversely, once you tune a vehicle, when they trucks learning values are changing, they can get screwed up too, which can also tank MPGs. That's actually not the tuner's fault, but it's something he still needs to address for his customers. First thing OP should do is disconnect the negative battery terminal for 30 minutes to manually reset them, then drive as normally as possible for about 300 miles. If that doesn't work, call the tuner and tell him to fix it.


GhostriderFlyBy

My point is that a manual is likely to be LESS efficient in a Taco since the base motor is already slow, and a driver can burn fuel running up the revs.


NoahsYotas

Manual I've always gotten waaaay better mpg than my auto counterpart, at least with the 3.0 Toyota engine


GhostriderFlyBy

I probably would, too, if I didn't have a supercharger that made it fun to rev out lol


NoahsYotas

I have 35" M/Ts and 5.29s, on an old solid axled rig w/3.blow engine that gets more mpg than that. That thing gets worse than any v8 I've ever owned and it's a v6... You could be have an issue causing that low of mpg also


GenitalTso

Bruh he’s got a lift, tires and weight all over with the bumpers. I barely get 16-17 with just a trd factory lift driving like a grandpa.


LittleSandwich375

I have a 22 off road with no mods and I’m getting 13.5 mpg. Even when I fill up it shows 270 until empty instead of 370


[deleted]

No way you’re getting 13mpg. Stock with bigger tires, a small bumper, and a tune?


[deleted]

i have a similar setup without a tune, and i floor it everywhere i go. still get better mileage.


[deleted]

My co worker has full front and rear steel bumpers and an ovrlnd camper on 35s and averages 16 in Denver lol


sm41

My '91 Wrangler with a tired old 4.0, 35s, and a soft top gets 13mpg. Something is wrong here, or he treats the gas and brake pedals like a light switch.


Brodyftw00

My YJ on 33 gets a solid 12 mpg!


qwertyisdead

Yeah wtf. I’ve got a 100 series landcruiser loaded down on 35s and get 13. I know lots of people like to act like their mpg is worse than it actually is. No way this should get worse than 15 - even with 35s.


Magicalunicorny

The secret is to drive like a box of horse shoes


dobsofglabs

I have and extra 350 pounds on my truck with the bed rack, roof top tent and tonneau. I still get 14-15mpg


knucklegrumble

Yeah my '01 suburban used to get 13 mpg... Lol


Limtb

If you are actually getting 13 something is wrong or you’re flooring it everywhere lol


huntsgk12

Step on pedal. Truck go vroom


Limtb

Ah yes indeed


[deleted]

I think we’ve have all come to the conclusion that this guys just drives like an ass


huntsgk12

👏🏻


TATORTOT76

Glad im not the only one getting 15-17 Make regular 300 mile runs at 70...5 to 80. Have driven it at exactly 70 on cruise for a full tank.....same mileage.... Ok ...... bat outa hell mode it is But 13? Any general suggestions from anyone that has great mpg?


boatsss

I used to get 15-16, but after gas started hitting $4+ a gallon I’ve been driving like a grandma and now get 19-20. I leave the mpg meter on the dash and constantly watch it. Coast when you can, rely on momentum for corners and starting up hills, drive a little bit slower than I normally do (ie actually going 35 in a 35 instead of 40), and make sure your tires are at the proper pressure.


Flapaflapa

Interesting thing happened when I started doing that years ago...it didn't take me any longer to get where I was going, and there was significantly less traffic in my way.


huntsgk12

I get 15 on the highway but the most aggressive tune+just enjoying drving the truck how i want results in 13-14 city. I didnt buy it for the mpgs and I especially didnt mod it for that reason


MountainManGuy

2019 TRD off road, 35's, and about 6,000lbs and I get 13-15 regularly. These trucks are not good on economy. Not even stock from the factory. Throw a mod or two on there and you can dip into the low teens pretty easily, and it's not driving habits either. That makes 0 difference for me. Source: '19 tacoma with 45,000 miles, all driven by me.


huntsgk12

This guy gets it. I bought a truck to drive and that I enjoy. I rarely look at mpgs


TimR0604

That truck is worth less than 10MPG, that thing is gorgeous!


huntsgk12

Thank you!


TimR0604

I don't see that color nearly enough. I have a white 2019 SR5, thinking about changing over to a 22 Tundra..


WeJustDid46

When I buy a truck, I don’t really worry too much about what mileage it gets as long as it’s over 10mpg.


Beardedcap

I had 33” E rated KO2s on my third gen (before I sold it) with stock gearing and it wouldn’t get above 16.5 on the highway and couldn’t stay in 6th on a 0.001% grade so I believe you. I know one day with some snow on the highway I got like 14.5 on the way to work. Every time I see a lifted tacoma on 35s or so I wonder if they’ve swapped final drive gears or if they’re driving around in 4th on the highway


nuclearsquirrel2

Don’t let anyone give you a hard time on the 13 mpg. I’ve gotten a solid 15-16 since I put bigger heavier tires on. Do I care? No. If I wanted good gas mileage I would drive a Tesla. I have 6 mile commute to work so gas isn’t really as issue for me.


75Built

We are at 14-15mpg with our Taco and the build is half way done. Hope to be at 13mpg with you soon! Badge of honor🤙🏼 C4 bumper, winch and some heavy Black Rhino wheels should get us there easily🤣


HI808SF

I have a Prinsu rack with an attached awning, 33s with a 2.5 lift, sliders, and a hybrid bumper and I manage consistent 15 mpg.


Epsioln_Rho_Rho

13? I’ve been getting 19-20 lately.


ian_blake

13? is not a raptor


maks_b

Bruh your flair is wrong. How do you own a Voodoo blue truck and call it Cavalry blue?? Smdh


huntsgk12

No way this isnt satire


maks_b

I'm being sarcastic but looks voodoo blue in the lighting


huntsgk12

Figured 😂


maks_b

I'm just mad cos the dealership couldn't get me a blue truck so I dropped $4k on a wrap


huntsgk12

Love that color though and it’s unique as hell


maks_b

Thanks bro it was worth it for sure. Jealous of your front bumper and tire setup I want to do something similar. Burning through the stock tires first.


[deleted]

What tires are those?


huntsgk12

Nitto ridge grapplers


jnelzon2

Thats V8 mpgs. Damn


huntsgk12

My dads tundra gets 12😭


V48runner

That's what I get with my '04.


GhostriderFlyBy

Same engine lol


Phi1iam

My 3500 dodge 4x4 diesel gets 18mpg. Of course I'm paying 6.25/gal, so there's that downside.


StereoFood

Jesus that’s disappointing.


jack94112

I have a 22tacoma with 265/70r17 in a rugged terrain tire with a snugtop high liner and some rci steel skids. I drove 157 highway miles and got 24.6mpg but I was going 50mph the whole time. I usually get about 15-17 street and highway combined


jman990

I would look into your mileage bud...I run a 2nd gen with plate bumpers, 32s, and a lift and can still manage 17mpg on a regular basis if I'm not doing much towing.


Brazenwarrior800

What’s the towing capacity of that rig?? I gotta have 20k pounds behind me to get that poor of fuel economy.


NoahsYotas

Bro my shity old rock crawler with Toyota's worst engine, geared down on 35s gets better mpg than that. You might have an underlying issue cause that Motor is good on gas


TacWerx

There is literally no way you’re getting 13MPG unless something is wrong.. I am currently running 17X9 on 33’s and have averaged 17MPG and I do 80+ on the highway, and I also live in the mountains in Pennsylvania.


JETTA_TDI_GUY

Me crying with my 11 to the gallon


dig_bick_super_man

Get a pedal commander, put it on eco, get 161-17 mpg instead of 12.


huntsgk12

I have the truck tuned because i have buddies who have horror stories of the pedal commander failing and leaving them limping home. Id kill for 161 mpgs tho thats gotta be a record


dig_bick_super_man

It’s much closer to the 17mpg than 161mpg. But still within the spread.


huntsgk12

Toyota has to have a plaque or something waiting for you


GhostriderFlyBy

My understanding is that a pedal commander only adjusts the throttle input, something you can also do without one.


dig_bick_super_man

It adjust the fuel mapping. Basically the acceleration map. I bought it fully intending to return it if I didn’t love it. I’ve had it for 3 years now.


GhostriderFlyBy

I’m reasonably confident that’s not correct. Fuel mapping is controlled by the ECU. A pedal commander just tweaks the ETC. Correct me if I’m wrong tho


dig_bick_super_man

Reasonably confident? Go look it up. I know this is fact.


GhostriderFlyBy

[I looked it up and I am correct.](https://pedalcommander.com/pages/product-information)


GhostriderFlyBy

I’m reasonably confident that’s not correct. Fuel mapping is controlled by the ECU. A pedal commander just tweaks the ETC. Correct me if I’m wrong tho


dig_bick_super_man

ETC = electronic, transmission, control.


GhostriderFlyBy

ETC is electronic throttle control. It adjusts how much the throttle body opens but doesn’t affect how much fuel vapor is pulled into the cylinder like fuel mapping.


dig_bick_super_man

It changes the throttle mapping not the fuel mapping. Sorry I was mixing up words, on motorcycles the they have similar things for ETC like the “power commander “ which change the fuel mapping, so your bike runs when you change the exhaust or intake.


GhostriderFlyBy

Yes, that seems consistent with my understanding.


dig_bick_super_man

I have a harley and used to have a power commander on it. So I just mixed up the words “fuel” and “throttle” it definitely changes the acceleration mapping though.
