So looking at 23-24 yr model Tundras and most people that have them are saying that the avg mpg they are getting mixed driving is 17-20 with stock tires.
Just wondering if anyone on here has gone a little taller tire with an A/T tread and what their real world mpg is now?

Thanks

Went from 32” stock to 34” e rated and lost a couple of mpg (on the computer). 16.5-17.5mpg mixed town/highway driving. Non-hybrid.

I run 34s on my hybrid and non-hybrid. There is 1mpg difference with the better going to the hybrid. But neither really ever avg better than 15-17mpg.

That's horrible mileage.

I’ll make you feel better. I get 12-13 mpg in my 2016 with 18s and KO3s.

The other question is if it’s a real hand calculation or letting the computer lie to you

I’m sure some are honest but I’ve never owned one. They always err high so you know it’s phony.

I love mine. No point of getting a hybrid tbh. Hybrids take up the storage compartment under the back seat.

I typically get 17-22 with my 23 on my nitto ridge grapplers

I just swapped from 265 stocks to 275/60/20s nittos. Too early to really know the difference bc I probably don’t have 2k miles on the nittos but… I get 19.5-20.5ish now at 70 mph. Stocks were 21-23. Mixed driving 17.5ish now but was in 18s stock. So basically the +1 nomad grapplers reduced about 1-1.5 mpg.

I agree. You can’t rely on the vehicle’s computer. That’s how I know Im getting 12-13, that’s stop and go city driving.

My 24 , stock tires , non hybrid, gets 16-17 every day driving/around town and 20+ on the interstate. I've checked it the old fashioned way several times and the computer is usually 1/2 to 1 mile more. Best ever was 22.1 coming across OK with a tail wind. I'm pleased with my mpg, not bad for a 1/2 ton gas burner with 390 hp.

I had a 2022 Tundra, and put 35’s and 2” lift. Once I made these mods the mpg dropped about 2 mpg. Averaged around 15 with mix of city and highway driving.

this combined city/highway? I thought the older ones got about 16 17 highway?

When you put on larger tires and you calculate your fuel mileage there is a factor you need to also calculate, because you are now actually travelling more miles than what your truck odometer is recording. For instance...

The circumference on a 32" tire = 8'-4 1/2"
The circumference on a 35" tire = 9'-1 15/16"

So if the 32" tires were OEM and now you have 35" tires, every time your tires make one full revolution you are travelling 9 7/16" more distance than your odometer is recording. That really adds up. Which means you're actually getting better fuel mileage than your computer is telling you or your calculations are telling you unless you factor in that additional mileage you are getting with each tankful.

Ditto with my 2010 with 18s / Goodyear Defender LTX M/S
I believe the leveling kit I put on the truck degraded MPG as well

You can recalibrate the computer on newer trucks for a different tire size.

The manufacturers put on the tire which results in the best EPA mileage rating. When I bought new tires for my current truck I put E rated Nitto Ridge Grapplers on it that were the same size as the OEM tires. My MPG dropped by about 3 MPG.

Going from a 33 to a 35 cost me roughly 2mpg

Yeah. I did this on my Jeep Rubicon. I did it mainly to help with the transmission shift points, which still suck, but they suck less than they used to. I think the device to plug in and recalibrate it cost me like $100 bucks or something like that.

I'm kind of a nerd, so just about every time I fill up I take my trip odometer mileage and divide the gallons into the mileage to get the accurate mileage, then I reset the trip odometer at every fill up. This is the only accurate way to check your mileage that I know of. My calculations always show better mileage than the trip computer does.

I do the same. The computers on my last two or three trucks have actually been pretty accurate, but ive had some in the past that could be off by 2 mpg.

I put a 6” lift and 33’s on my 2015 Tundra several years back. Average MPG is around 14-15, unless I’m pulling something. Then it’s probably 12-13 MPG. Thankfully this truck is not my daily driver.

Here’s my truck in its most natural state… 🙄
