i use to run 40 PSI on 265/35/22's on my old 05 chrysler 300 and the truck i traded in on my vette was running 45 PSI on 285/70/17 MT's as this was an accepted safe pressure when driving on city/paved roads (obviously much lower when taken off-road).

Based on all I've read on here, I keep my stock 01 C5 wheels with stock sized Falken FK452's at 30 psi F/R.
I do notice on the DIC, the pressures go all the way as high as 37 when it is hot on the highway, anyone else notice this?

I tend to run all my tires within 10% of their max PSI rating. I don't mind the rough ride and like the longer tire life + added gas mileage.
As they get older sometimes I will run them at recommended pressures (lower) to get better traction and finish off the outer edges of the tread.
Sometimes tire shops will over inflate so the new tires won't flat spot and the bead will seat better. I usually leave them over-inflated for a day or two.

30 psi is the correct pressure according to the sticker on the inside of the door. That's what I keep mine at and they wear very evenly.
