    How much air are you running in your tires? I have a '02 2500HD with stock tires (Firestones, I believe) which are rated for 80 PSI max cold. What would you run those at?

    you can almost answer your own question- how much weight are you putting on them? What weight are they rated for at 80PSI?

    I have my BFG's at 60 rear (with almost 1K lbs in the back) only because they local gas station compressor wouldn't get them any higher (should be 80 but tread pattern is fine so I may leave them) fronts are at 70-75 for the same reason as above- should be at 80 but again tread pattern is ok but I will air them up as soon as MY air compressor warms up enough to run.

    Look at the pattern the tread makes in the snow to deturmine the proper pressure- you want a flat even pattern- same pressure rules apply with the extra weight of a plow as to a passanger car. Too little pressure and the sidewalls rub- center tread is weak imprinted. too much cna the side lugs won't bite as well.

    in the winter when I am running a blade and ballast i run the max inflation listed on the sidewall of the tire. In the summer I air down a bit for a better ride since i dont carry much weight.

    Max psi rating on BFG AT KO is 65 psi.

    You guys running 80 psi are asking for trouble.

    In my 01 and 02 HDs I have 65 psi front and rear.

    I drive a 2000 F250 diesel and always run The manufactures recc's (80/60) But sometimes softer on the front end. Depending on conditions.

    Tire pressure

    What if you have a full load of salt 3-4 yards, and it calls for 80 psi. Do i take it down?

    Running tires under inflated can cause major problems like broken belts. I run the tires max rated pressure on all trucks. I also carry my spare overinflated by 10 psi.... When changing a flat it's easier to let air out of a tire, than try to put air in.....

    Oh yea, my BFGR All-Terrain TAs are load range E and require 80 psi......

    You guys running max. inflation can do more harm than good. You only max out the inflation when your tire carries the max load, which for a 235/85/16 is 3000lbs. 80 PSI is the MAX.the tire is CAPABLE of holding WITH THAT WEIGHT !

    Not just "Max" load but even partial load... And my trucks go out with 1000lbs ballast plus 1500 to 2500lbs of salt.

    I don't have problems with tires de-laminating(blowing out) since I started keeping tires fully inflated.....
