Not speaking from any technical point of view, just experience.....
Running BFG MT 31's on standard Wrangler alloys, aired down to 12 psi & popped a tyre off a rim in deep ruts, may have a little too keen on the loud pedal to clear the obstacles but I ain't aired sown since

PS, no hairspray needed, just re-inflated with our compressor & it popped back in place a treat, lucky I guess
