Im running 37's, and if I run anything lower then 35 the tpms lights come on. I know it doesn't hurt anything. It just bothers me. What psi Is everyone running?

 

depends on tire size, vehicle weight and load range. Do a chalk test and see where you need to be. I run about 18-22 on 35"s load range e

 

I run ~27 with my 315/70/17 load range D.

x2 on what Maertz said. It all depends on how heavy your rig is, the load range of tires, and tire size. The best way to figure out what psi you need is by doing the chalk test.

 

im running good year wrangler gs-a not sure the load range, i'll look it up, but im thinking my psi is way to high right now. Its 37ish

 

Try airing down to about 25 and go from there.

 

Mine are load range e. Does your tpms light stay on because of the lower psi?

 

Don't have tpms.

I believe the Superchips Flaspaq can turn off tpms.

 

ah lucky you, anything under 35 psi I get the warning lights

 

Let me guess, running an unsupported Dana 30 too? JK, 37's require a lot of work to run them properly, one of the first upgrades should be a Procal (or similar). This will reset the computer for correct odometer and speedometer readings. You'll be able to adjust your TPMS settings to a lower psi too.
