    I just installed 235/75/16 10 ply tires and max air rating is 80 psi. Are you guys running that high without the load ? What pressure did you bring it down to. Besides it feeling like your sitting on a moving rock, is it ok to leave it at the max ?

    Tire pressure

    I've always run my load E's at 80 PSI, Except when I went on the sand in the OuterBanx then I dropped them down to 20 PSI. After I had been to the dealer one time some moron set them at 55 PSI and I did not realize it until much later and I noticed the tires wearing funny. Sooooo, if I were you put'em at 80 PSI.

    So you think running them lower without a load would wear more?

    really not a good idea to run at max psi with no load, tires will wear in the middle

    I run mine @ 60 all the way around. I've been told that GM has to suggest max psi to cover their liability, and they have to assume that the tire will be used to it's maximum capacity. 80 psi is just way to hard of a ride.. I'll take more wear as a compromise for better ride quality. Unless you're towing a fifth wheel or heavy trailer, I'd experiment around 50 - 60 psi and see what works best with your truck.

    Yes, I think 60 psi. is a good compromise between ride and load ability. Works for me.

    I keep the rears at 50 PSI so they wear even and last longer.
    The fronts at 60-65 PSI is good. Then I raise them to 75-80 PSI with the blade on.
