What tire pressure are you running?
Curious because I saw in a recent post that someone was running 45 psi for mileage purposes.
I run 32 psi on 235/75's

you are supposed to run what the vehicle reccomends. not the maximum pressure as stated on the tire.
with that said. when fitting larger tires sometimes adjustments need to be made for proper wear, ride, handling, etc.

Lol, I think the OP was talking about on-rod psi's. For me, I stick to 30psi for my 31's on pavement. Offroad it depends on 2 things - tire width and rim width. If you've got a 12.50 tire on a 8" wide rim, you can go down to about 10psi and not worry about losing a bead on off-camber stuff. If you've got beadlocks though, run the things down to 4psi.

stock about 32psi
31's about 28psi
33's about 25psi
36's about 19psi
your jeep is a lot lighter than the truck your oversized tires were designed for, so less pressure will be needed.
too much pressure, and you risk crowning which will result in center tire wear and poor road handling.
too little pressure and you risk cupping of the tires which will result in outter edge tire wear and poor road handling.
there is always the chalk method, where you scrub the chalk across the tire in as much coverage as you can, then drive around the block and inspect where the chalk was rubbed off. adjust tire pressure according to above cupping/crowning.
