    I've run 35psi ever since I got mine in '97. It isn't a daily driver, more like a weekend warrior. Anywho, they are 33"x12.50x15 BFG Mud Terrains on 10" rims. I've had very good wear with the exception of when I didn't have them balanced after a wheel (rim) change. Rotate them frequently, keep 'em balanced and aired up and they'll last forever. (allmost)

    And fill out your profile so whe know what you drive. :)

    Re: tire pressure for bfg\'s

    First off you need to look at the side wall and see what the max pressure rating is. I have 31 A/T's on my wifes and 32 MT/s on mine. These tires are rated 50 PSI. On these tires I'm getting the best wear at 38 front 36 rear. The MT's have about 25k on them and have worn even at those presures. NOW FAIR WARNING GM Rally wheels are rated 40psi. it's stamped on the rim.

    I would think it would have alot do with your suspension. im running RS9000, and a 2.5 trail master spings, As i said mine runs very nice, Now i had a 76 truck with a 4in with 3in body lift now that rode like a tank.

    Drive it like you stole it !

    Re: tire pressure for bfg\'s

    i agree with goose keep them balanced and rotated is the most important thing i am not running bfg i am running wild country mud tires and i run 32psi and i rotate and balance often and they are wearing even. i have about 20,000 miles on mine and they still have about 90% tread left
