Thread: Tire Pressure??

  1. #1

    Default Tire Pressure??

    I have an 04 Chevy Silverado 1500 quad cab. I have BFG LT285/70R17 All terrein T/A KO's. What is a good recommended tire pressure for everyday city/highway driving. I checked the manual and the door but they do not have any specs for that tire size.
    Just a yank in the heart of DIXIE

    On the sidewall of the tire you will find the maximum tire pressure recommended by the tire manufacturer. This pressure would be for full load conditions. You can come off of that for a softer ride.

    For years I've used the trial and error method to get the best for me tire pressure.
    Load the truck with whatever you carry on a normal day.
    draw a heavy chalk mark across the pavement in front of all 4 tires leaving lots of chalk down.
    Roll over the chalk marks then read the tires.
    Chalk in center only = to much pressure
    Chalk on outside edges only = to little pressure
    Chalk evenly across the whole tire tread = right pressure
    After I get the tires in the right range of air pressure I fine tune the pressure by adding or removing a lb at a time a after driving. Once you get the feel just right note the pressure of each tire for future reference.
    Each tire will probably have a slightly different pressure but that's to be expected since each tire supports a different amount of weight.
    Sounds like a pain but the method works great and has enabled me to get high mileage from some expensive off-road tires.
