What's the recommended tire pressure for J treads? I have them set at 34 psi, but my "low tire" indicator will not go off.

 

38 PSI is what I run for daily driving

 

It kind of depends on your tire size. A chalk test is the best way to determine if your tire is properly inflated. I have 35" ProComp MT's and if I want comfort I have to air down to 30psi, if I want fuel economy I go to 35psi. I use a AEV ProCal to turn off my warning light. Also not all pressure guages are accurate.

 

26-28psi usually to get even wear and screw the pressure sensors. Never put any back on after going to 35s, they just aren't worth it. The idiot light can stay on forever lol

Depends on your tires size though, do the chalk test and figure out what's best for your vehicle.
