I'm running 35x12.50R 17 NITTO TRAIL GRAPPLERS and need TIRE PREASURE HELP! What have you found to be the best tire pressure on a 2 door 2007 Jeep Wrangler X? I have a super chips power programmer and can't seem to get it dialed in just right?

 

I'm running 30-32 and it rides great so far, but just got them on yesterday.

 

Most people are running between 28 and 32 psi.

 

28. How low have you been testing?

 

For about 3 weeks. It seems like I can't hit the mark. getting the shift points to hit where they should between the programmer and the tire pressure.. I got the tuner on tow, and have tried every combo possible.. But my 07 is rare as it has Dana 35 rear with 411 and Dana 30 front with 410s.. About ready to put the white flag in..

 

I run 26# in mine for about 3000 miles

 

Ive got 35X12.5X17 mud grapplers and run them at 28. Seems to work good for me.

 

I'm running 30psi on my mtz. Thinking of going to 28 but the tread wear seems good atm

Haven't had time for the chalk test but most people run 28-30 on a 35

 

I am running 30 in 35 x 12.50 Trail Grapplers on my JKUR and they ride better than the stock BFGs.

 

are you asking for tire pressure so you can calibrate the speedometer and transmission shift points? what steps have you done to try and "dial it in" ? are you also using a gps to help calibrate speed?
