Tire Poke Gas Milage Drop

[Dead Horse]

I swapped my factory OR wheels for Trailhunter wheels, they poke out quite a bit more than the OR wheels did. I've noticed no significant change in MPG, all other things unchanged from before the swap. Factory tire size.

I think other mods and larger tires contribute a great deal more to fuel economy decreasing than tire poke alone.

I read somewhere that AT tires actually have less surface contact than a lower tread stock type tire and get a bit better milage for the same size tire.

tread contact patch is not what you are looking for. its the rolling resistence of a tire plus weight.

a/t tires tend to have a higher rolling resistence and are heavier than normal highway or all season truck tire vs an a/t or r/t truck tire.

so if really dont do ANY off roading, its better to go with a SL tire vs C/D/E type tire.

While SL (Standard Load) and C-Load (6-ply) tires may share the exact same tread pattern, their internal construction and rubber compounds differ significantly. SL tires are optimized for comfort and fuel economy on passenger vehicles, whereas C-Load tires are built with stiffer, reinforced sidewalls for heavy hauling, towing, and off-road durability.

I have seriously stopped carrying about MPG on mine as I start adding more stuff and getting closer to GVWR. I started thinking more of it as SPG instead; Smiles per Gallons.

I removed the fuel economy gauge from my dash last week. I like my bigger and wider tires so the only thing I am tracking is my SPG lol

I too like larger tires and a usable off road suspension but I still care about gas milage. If I'm not adding performance and its just for ascetics I don't care much about it.

Unfortunately, in the history of modding those two (larger tires and off-road) have never resulted in better or even good gas mileage. It's the nature of the best.

personally i think what you are looking for is the dueler a/t ascent

its a recent new hybrid all season / at tire


rugged a/t thread design but more of all season / ht tire


even the c/e loads are eco focused which is untypical

it was a toss up between the a/t ascent rugged look and the ltx ms2 superior pavement manners, decided the ms2 since i might do 1% off pavement driving so no point getting the ascent's

I totally understand the loss of milage with larger tires, I just don't want to make the milage worse without performance gains. For instance do I need a 35" tire on a new TRD Pro or can I do 99.9% with say a 285/75/18 that is only 1/4" less diameter and over 1" less width, less weight and much less rolling resistance. I have read a lot of the articles posted on here and on 5th gen forums about "pizza cutter" out performing wider tires. Not that the above tire is a pizza cutter. This will be my 5th 4Runner.

The wide vs narrow argument is as old as tires. There's one camp that will claim that narrow tires are better with rocks while the other camp says wider tires are better in sand. The truth is right in the middle, just like any other argument.

Pick the best tire for your style of terrain that you go off-roading. I will bet pennies-to-dollars that you will see both in the same terrain and they will both do about the same.
