You guys running nittos. What psi are you setting the tires too? This is a daily driver. Just need some input.

Im at 29 to 30 on road for the 2 door. Off road, if you do not have beadlocks i would run no less than 12 to prevent popping a bead off.

37x12.50 17.

30 on road, 15-16 on trail. I've never felt the need for more grip so no need to air down more. As they wear more I may go a lil lower but these things are amazing!!

Around 26 on my 2dr on the street. That's the best I found with my chalk testing.

I ran 8-10 psi non beadlock and 2-5 with beadlocks depending on the terrain I was running.

You guys running 30 psi how was your chalk test? Mine ran on the centers at that psi with the WE beadlocks.
