    Which for my '08 2500HD is 65 psi. As said, pulling a fifth wheel adds little to the front tires. In fact, for my set up the static load is the same hooked up or not.
  • When towing my 5'er: 80 rear, 60-65 front
    When now towing: 60-65 front and rear

    I have load range E tires as most 2500HD's do.

    80 rear and 72 front if it is a Cummins and 65 if GM or Ford. Cummins is heavier.

    Run 45 in the rear. Leave the front towing or not. The front changes very little with a 5er.
