30-32psi gets my vote. Anything higher will probably get some speedy wear in the center.

lately ive been filling to 32 when cold. Heats up to about 34-35 while driving.

Seems the sidewalls/outside were getting worn faster from running at 35+PSI.

If they are street tires I would run 30-32. I ran 21-24 on my Nitto's DD'ing them and the center still wore out!

I run my BFG's at 30 cold. Anything more and the ride starts getting harsh.
