Default Nitto Mud Grappler Tire Pressure Questions???
I was wondering what others are running for air pressure. Tire shop put 37psi in just to match what the TPMS is set at. I think it should be less, but i will have to reprogram the TPMS.

I lowered to 34psi and rides better, and the TPMS light is NOT ON. I wonder what the psi is that makes the TPMS light come on.

At 34PSI in the summer, my TPMS light only comes on when it gets cold (<0C). I'm guessing the TMPS sensor is at 35 ish.

Well, mine are only 35s, but I'm running em at 25psi. No sidewall flex, great ride. I need to do a chalk test, but I think I'm pretty close.
