It is all in how your tire hits the road. Jeeps are light, without any armour on them, and just because the tire company rates a tire at 32 psi, does not mean that is where your tire will give you the most wear. Look at your tires, and see how they sit on the road. If the only part of your tire that is touching, is the center of it, it has too much air in it. Mr. C made a good point, in another thread. Do a chaulk test with your tire, and make sure it hits evenly, all the way across.

I would think that 38 lbs. would be way too much.
I only run 30 lbs. in our Rubi. But that is with 12.5" wide tires.

Very good point, I try to keep them at 30-35 its what feels best on my jeep anyway.

I'll try the chalk test when I get some Chalk.

I routinely run my tires on any vehicle at 5 under the tire manufacturer's recommended pressure. Don't use the vehicle maufacturer's recommended pressure or you will be running too soft in my opinion.

Chaulk the driveway heavily, wide enough for the tire to run over it. See how the tire imprints your driveway, when the chaulk on your tires rolls back around.

I run my 31 BFGs at 32. They seem to be wearing nice.
