245/75/16 E vs 265/70/16 E on a 2.7

should I stick with 245/75/16 load range E or get 265/70/16 load range E on my 2.7 Tacoma, does anyone know how much difference it would make if any ?

 

Any time you increase the size/weight of the tires there will be a difference. Less fuel economy, slower acceleration. The bigger the change in tire, the more drastic the affects.

It all depends on what you want out of your truck. Is there a particular reason you want to switch to 265/70?

 

Well I’m getting a 2 inch leveling kit for it so I want a tire that’s alittle bigger

 

Not to hijack but I have the question... but I went from stock steel wheels to some Scs rays. The Scs weight a few pounds less than the steelies so if I decide to make the same tire change that OP is wanting to possibly do, would the weight difference make up for the tire size and = minimal mpg loss?

 

why do you need a E rated tire for?

 

The tires are the same height. The 265/70/16 is about 1" wider. I've run both sizes on my Tacoma and couldn't tell any difference. I've also ran 265/75/16's which are about 1" taller and couldn't tell any difference. I've run both P and E series tires. No difference in ride, performance or fuel mileage. Just looks.

I do have the 4.0 but can't imagine you're going to see any difference with the 2.7 either.

If you want a slightly bigger tire you want 265/75/16's instead of 245/75/16's or 265/70/16's. They will be 1" taller and 1" wider than the 245/75/16's. And you don't need a lift, that size will fit a stock truck. A 285/75/16 will need a small lift.

What is your gear ratio? I'm not as familiar with the 2.7's. Virtually all 4.0's have 3.73 gears and aren't terribly affected by small increases in tire size. I'm thinking the 2.7's have 4.10's which will be even better. If it is less than 4.10 then you might have some noticeable power loss.

 

I don't see how a you'd notice a difference. Super slight if you notice it at all.

Take into consideration the above ^^^^ numbers @65 mph are 1:1 trans ratio and not overdrive.

I went from 245/75/16 to 265/70/17 on my 2.7 (5sp) and there was a small noticeable difference.

 

Just put 35s on it'll be fine I promise

 

For the money and since your going to be “leveled” I’d look at the 265/75/R16s. It’s going to be a touch cheaper than any 265/70 as the 75 aspect ratio is LOTS more common.

I have a 3rd Gen OR suspension under my 2015 and it raised my front about 1.4” or so and I run a 265/75/R16, 4-ply.
