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.
