What tire pressure do you guys usually run in the trail grapplers 35's ??

 

for a 35, i would say about 30 psi

 

For load range E and D tires on a JK or JKU you can run anywhere from 27-32 PSI on the street. The lower the PSI the better ride you will get in that range, but some people do a lot of HWY so they are more comfortable in the middle to high range. I run right about 30, but sometimes I will run 28 for a nice smushy ride.

You will probably need a PROCAL or tuner to set your TPMS threshold lower if you run 30 or lower.

 

I run 30 in my 315/75R16 D rated Maxxis Bighorns. Seems to give pretty good wear, ride and fuel economy. Anything more and you can see noticeable wear in the center of the tire and a very bouncy ride.

 

Run a chalk test and you'll be able to dial in your psi. Search the site, plenty of info on how to do it.

 

Yea im still waiting to see if procal will work with my 12

 

It will...

 

X2...mine is a '12 and it works.

 

Procal worked perfect on my '12

I am running 32 PSI on my Load Range E 35" MT's. Its a bit bumpy but I do mostly highway driving and prefer the better gas mileage.

 

Why is the max pressure so high?
