Tire Pressure for ProComp 35's?

I'm running ProComp Xtreme AT 315/15 r16 (load range D) on 2011 JKU Rubicon with 3" puck lift. 80% tread remaining, and driven 90% on the highway. Ride is rougher than expected, and feel like tires may be over-inflated. I've seen tire pressure recommendations from 30 psi to 65 psi. What's the ideal inflation for these tires under these conditions? Thanks.

Search for chalk test. You'll prob end up somewhere in the mid to high 20s.

I have the same tires in 315/70/17 and run 28 on Hwy and air down to 16-18 psi off road. Rides well, but your tire sensors will not agree and will need to be calibrated.
