I have the stiff Toyo Mt's. 35x12.5x18's as well. Usually 26 on road, 10 off road. 2 door, not much extra weight. Stock stubbed bumpers, no winch, no rear seat/passengers. Works great, good ride & performance on & off road.

Just do a chalk test to find out. Chances are you will want to run them at 30 or under

Wow glad I thought to check them. Why run the psi so low? Also would the air being at 50 cause it to handle like crap? Also its a 08 with 2.5 lift not a bb 2dr with nothing else added on to it

Yes, too much air will make it handle and ride like sh*t!
