Tire pressure is going to depend on the weight of your vehicle and the load rating of your tire. The best way to determine the correct tire pressure for your rig is to do a chalk test.
Find a location that is flat and you can drive around 50 feet in a straight line.
Mark a section of your tire from edge to edge and around 2 inches wide with chalk.
Drive your jeep forward about 50 feet and then backwards 50 feet.
Take a look at the chalk on the tire. If the chalk is only worn off on the center of the tire, reduce the tire pressure slightly and go through the process again. With the adjustment, you should see the chalk wear off more broadly. Keep making tiny adjustments in the tire pressure until the chalk wears off evenly and all the way across the tread.
Many folks will mark their four tires so that they can get the correct pressure at all four corners. I just do one front and one rear and then run the pressure for front and rear the same for driver to passenger.
