    I settled on 30 psi. Handles good and rides much nicer than before. Thanks again

    let me ask you a question Eddie my buddy had the 2-in Mopar lift with the fox shocks and 37s(JLUR)and he could run it at 40 psi and it ran smooth as silk why is that is that because of the lift height or because of the shock setup or what?
    Mine are 28-32(cold-hot)

    The E rated tires are stiff to be sure. I run my Nitto Ridge Grapplers at 30. It seems thatís the best pressure for me. 37x13.50x17. If I wanted a softer ride Iíd have to go away from the E rated tires and thatís not what I want to do.

    Softer tire also equals a quicker wear down too right?

    They run lower PSI because it wears evenly. I use to run over 35PSI when i had Mickey Thompson tires and it wore in the middle.

    Put some chalk lines across the tread in 3 or 4 places on each tire and drive it for a short distance. If the edges have more chalk than the center, you are running with too much pressure. You will see that much over 30 is too much.
