    Maybe for a loaded one ton!
    I assume we are talking K5 here...

    35": run about 18 psi
    36" radial: about 20 psi
    38": about 16-18 psi

    These big tires don't need much pressure because they have a lot more square inches than stock size tires.

    When in doubt, do the chalk test. Chalk the tread and drive a little ways on pavement. You want as much tread in contact with the road as possible.

    Poundin' the ol "pavment"!

    Yeah, but due to the exchange rate, air is not as dense in Canada.

    BTW, didn't your swampers ride rough and wear out fast???

    That's the maximum inflation pressure, to carry the maximum safe load. That's not necessarily the pressure you should run, unless you're loading your vehicle to the max safe load limit of the tires.
    If the tire says 50psi and is rated for 2000lbs, but that tire only has 1000lbs of weight on it, then it's gonna ride like a brick and wear out the tread center long before the outsides.
    Best bet is to do the chalk trick, or the water trick (spray tire tread with light mist of water from an old Windex bottle, roll vehicle until tread leaves a wet impression on the ground. Adjust pressure until the wet mark is even across the tread.).
