I went out and dropped the psi on the tires to 35 all around. HUGE difference already. I don't feel like I'm riding the Flintstone's car anymore. Dropping from 43 to 35psi and driving for a few km's didn't even cause the TPMS to go off. Maybe it will go off if I drive around some more, or maybe I'll decide later to drop it another few psi once I get to do the actual chalk test, but so far so good. Wayyyy better ride. All thanks to your guys help.

 

I am running 35" toyos , I have the psi at 26 cold , even tire wear after 20,000 miles and the extra weight from bumper and things do make a difference , I had a really stiff ride , lowered the psi help , got my rear bumper help more , then front bumper , my wife said it's nice to ride in the jeep now , lot smoother
