I've read multiple posts relative to tire pressure. I have a 3.5" lift with 35s with recommended pressure of 36psi. When I bought the Jeep (used) with the suspension and tire mods already on it, the tire pressure was all over the place ranging from 34 to 44. The ride home on the interstate was interesting... I've since aired all to 36 and the ride has been better but after reading the posts, I plan to drop to 30. The tires are Fuel Gripper XT 35x12.5x20. Many thanks to all who have posted on this topic. Will let y'all know how it rides.
