How tall a tire can I put on my 2015 TRD OR?

Wondering how tall a tire will fit my 2015 TRD Off-Road truck. Just looking for a little more height clearance. 80% of my driving is highway, but I do like to get offroad 20% of the time. Thanks, guys.

Also, what brand and tread do you guys recommend for a semi-avid offroader?

 

265/75-16 is about the biggest. (Stock truck)

 

yup

 

Or 265/70-17. If you have a 17" Wheel.

BFG All terrain TA

our OR have 16 inch wheels

 

I couldn't recall. I know the TRD Sport came with 17's

 

yup!

 

Oh, another semi popular size is 235/85-16. Same height as a 265/75-16, just skinnier by 30 mm which is just over an inch. Skinny tires are good for deep snow, wide tire is good for mud, sand and rocks.

 

The only problem.....make sure you buy a spare the same size. You don't want to drive 25k miles. Forget you have a smaller tire and get a flat in the middle of a long trip on the back and throw a different size spare on the rear axle. Then, drive it gfor a few thousand miles and wonder why you need a new diff at just 60k....especially one with a locker. Just keep that in mind...5 of them !

My big argument with the 235 that high a profile is...it will handle like shit. Even the 265/75-16 will give up a little though it should ride better. That would be my number one choice as a wider tire will make the mileage worse then it already is.
The 265/70-16 does drive well. I thought about going larger too but, buying five, give up handling and increase final drive......just a little, I decided to stay with stock.

Plus, I run snow tires.....so mixing sizes would not be fun if you do too. Or...you buy nine new tires.

 

Jut get a cheap used tire of the same size off eBay for $20-30.

 

or switch a front tire to the rear and runthe spare up front

 

Somewhat true on handling. But it would be pretty tough to realize it. Plus, IMO it's a truck not a car. I'm one of the few left on this planet that expect a truck to be a rough ride and am completely ok with it.

 

This may be the world's stupidest question.. but why would different sized tires mess up a differential? I thought that was the point of having a diff to begin with...rotating at different rpm and all

 

Two tires of different diameters will have different rotations at the same speed which is bad for a ring and pinion. Circumference is different in tires.

 

How would the diff know the difference between that and a long shallow turn?

 

It wouldn't really. The bigger issue is driving straight.

 

It would be like turning left or right sharply for miles and miles at a time. It causes more heat in the differential. You'll be fine for a while, but eventually it will take a toll on the differential.

 

It's supposed to be 255/85-16 The only 33" tire that can fit without rubbing (stock is 31").

Skinny tires on deep snow is debatable. Seems to me that any terrain that benefits from airing down will benefit from a wider tire.

 

Now I'm confused. I would love to run this size on my stock 2011 TRD OR. I've read that "255/85 owner experience" thread about 3000 times to figure out if that size would fit w/out rubbing.

Now, this isn't scientific, but when I simply look at my wheel wells with my current 265/76/16's....there looks like plenty of room for 1/2" on each side of the tire..even with Husky mud flaps. Again...this doesn't account for the tire in a turned position....I guess that's the rub.

 

You also have to remember you get interference with the UCA.
