Ram recommended tire pressure

I just acquired a 2012 Ram 3500 H.O.. Sticker for rear tire pressure states 45lb for light load and 65lb for heavy load. I am used to going 80lb for my old F250 2500. At 65lb the tires seem to squat a bit. Anyone have this truck and can offer suggestion?

    DRW or SRW ?

    17" or 18" or 20" ?

    What tire size and load range ?

    Are they the OEM tires ?

    Makes a difference.

    Who would know better than the engineers that designed the truck? I follow the numbers on the door post sticker.

    My 2014 Ram 3500 door sticker says 80psi on the front steers, and 65psi on the rear duals. Ive done fine with pulling.

    So do you run over 9,750# on your 4 tires? That load only requires 65psi to more than meet that load with 4 tires. Running full psi is NOT always the best option.
