Tire pressure for 35/12.5R18

[R.Taylor]

What are people running in these? I have Cooper Discovery STT's with a D rating on my new rig (not by choice). I'm running 45psi all the way around, Should I go higher?

What size wheel are you running? I had 325/60/18 on 18 x 9. 5 Eagle Alloys, I was running them at 60psi front, 55psi rear, started wearing the centers off them. I dropped them down to 50psi front, 45psi rear and that helped. It was kind of a pain, because then I always had to air them up when loaded.
