Default Tire Pressure Advice

I just bought set of Pro Comp AT's in 315/75R/16. I'm curently running 35lbs in each and they seem to wonder slightly. I also installed a 4in lift as well. All are tracking straight in alignment. What might a better pressure be. These are on my DD. Any advice would be appreciated.
Thanks,
MTNBKR

I have 315 70 17 Duratracs (35'') and i run @ 30psi. For daily driving i found it good, but all depends in your Jeep weight. I have heavy front and rear bumper, plus tire carrier and the spare plus winch and rock slider. So for me @ 30psi is nice.

The best way to find the right psi for you is doing the ''chalk test''.

Good Luck!

that's a lot of air for that size tire. you really should be closer to 28-30 psi as mentioned and a chalk test would verify that. as far as your wandering goes, how much caster do you have. if you haven't set it after your lift, that is your real problem right there.

Good to know. I've been running 35 since I bought them. Seems to ride fine. Guess I'll do a chaulk test.
