10 to 15 psi you should be safe anything lower and you will chance losing a bead. I ran my 285's mounted on stock sport trac wheels down to 12psi with out any problems.

ABSOLUTLY NO LESS then 15 psi. If you go any lower you risk damaging the tire.

Good luck getting a warentee claim on 4 tires with damaged sidewalls. Also have fun when that thing blows out on you at 70MPH.

no problemo
the way manager said it is "all i know is you ran them too low for too long"

and my buddy pins his tires between rocks and slash's the sidewalls all the time and gets new tires.
