rics1997 If the 285/75/17 was in the size of a tire I like, I would much rather prefer it myself. I know many don't like the so called pizza cutter but to me they are a much better tire in most situations. Of course there are a few cases that a wider tire helps but for the most part a more narrow tire is much better. Not to mention the rolling resistance is much less and will get better gas mileage

If you like the tire that comes in the 285/75/17, I would go with it myself

What lift are you getting?
I'm going for AEV. It's been a toss up between AEV and RK's 2.5 Max Travel for about 3 months now. What put AEV over RK for me was the on-road handling AEV is noted for (i drive a lot of blacktop miles) and the fact that AEV uses progressive springs front and rear. I don't get into the rocks (only mud), so suspension travel isn't a factor. I don't believe anyone can go wrong with either lift.

These are the industry standard. You need two pairs.

Check the torque at each tire rotation.

Stick with a high quality brand, spidertrax is a good bet.

I appreciate everyone's comments....and now think I'm gonna go with the 35's. since the 285/75's are rare birds, the cost is really close to a 35" tire - like the Duratracs. I like the 35" Duratracs because of their weight....,again...I want max power/mileage I can possible get with doing a lift and bigger tires (without modding the engine or gears).

Don't let the door hit ya. Wait, on second thought...

OP> Once again, if you have the tire clearance, get the 315 Duratracs and never look back. The difference in engine performance between them and the 285 Toyos will be nil.

i82much No matter how you look at this, you are splitting hairs on the tire size. You've got plenty of suds with the 3.6 and 4.10's, pick the tire you like best and go have fun.

Also OP, I would go for the Duratracs. Super tires, can't go wrong, and yours are 3 ply. I wheeled the 2 ply a ton and put them through hell before I finally killed one. They work well off road and are the best on road tire I have experienced.

I'm looking at several of our sites and it looks like there is only about 1-3 options in this size. Not a popular size by most accounts for sure. This is an odd ball size, the standard is usually 285/70/17.

All of the tires mentioned in this thread are well under 34" once they're under load at the proper psi.

A 315 is taller than either variant. My recommendation is to skip the fractions in height and go for the tallest tire option here asked by the OP.

paleh0rse Under load, 75's are usually about 0.2" taller than 70's.

If you have the lift to handle it, just get the Duratrac 315's and never look back. If you're dying for that extra 0.2", then get the 315/75/16" version instead of the 17" version...
