    ONLY 33?! :eek:
    It should say on the tire what you should run. I'm guessing 55-60psi.

    check in the glov box, it may tell you there or posability on the door post. if not it is in the operators manual. The side of the tire says what the tire is rated for not what is recomended for your truck.

    If your in danger of overloading your FRONT axle (and most of us here are), you'd be best to inflate an E rated tire to at least 90% of it's max inflation.

    If your in danger of overloading your REAR axle (and most with salt spreaders do) you'd be best to inflate an E rated tire to 80 psi.

    Those with lesser than E rated tires, I'd say you'd better have the MAX pressure in the tire, as you may be over the weight capacity of the tires. That's not good.

    A regular cab gasser with a heavy plow will take it's FAWR close to 4400 lbs.

    A Crew Cab Diesel with a heavy plow will take it's FAWR over the 5000 lb mark.

    Forget what the owners manual says, it is for the tires that came on the truck. If you have different tires you may be way over inflating or way under.

    Real easy, if you are going to load your vehicle(plow ect) then put the max pressure the tire has listed on its side wall.

    Shouldn't you set the pressure when the truck is loaded?? Like with the plow and ballest in place. (fyi...I usually run mine at a little below max)

    5000 lbs in the bed of my 01 did not change the psi of my rear tires. Checked with a digital gage that reads 1/10...... :) :)

    I don't believe that would make a difference, the tires give enough that the pressure stays close the same. You could adjust it depending on whether you will be running loaded or not for comfort and handling. Check your tires and decals as mentioned and work within that range.

    I just checked all mine today and put 65psi. in each one. My digital gauge is accurate to 1/10 of psi.

    As written on the tire sidewall of the tire?
    Why not put them up to 45?

    What are the size numbers and weight capacity that are written on the sidewall of the tire?

    And what truck is this on, and what plow?

    I run my tires at the maximum rated pressure. The truck will never ride like a Cadillac even with soft tires.

    Current LT255/85R16's run 65psi, the original LT235/85R16's were 85psi...

    You guys act like its hard to let air out in the spring when the plow comes off! Put them up to the max rated pressure and you don't need to worry! Also remember that when temperatures get lower the pressure in your tires will drop slightly too, so when its bitter cold and you are out plowing the pressure will be a few pounds lower than it is today. Basic physics class. Then if you want comfort for the rest of the year, lower it in the spring again.
