    Just curious, for everyday driving, what kind of tire pressure is everyone running with their 285's? Thanks!

    36 is perfect. This would increase mileage per gallon.

    If the max air pressure is 50 or 51 PSI, you have a C load range tire.

    You are probably best going with the same air pressure recommended on the sticker in your driver's side door, but you could get away with a couple lbs extra. 33-36 PSI is probably pretty good for those tires.

    To find out what's best regarding wear, you should perform a chalk test.

    Say thanks to @csuviper - this is his how to!
