? for tire guys

I've never heard of a tire blowing up from too little PSI...that probably has something to do with it.

I wouldnt go any under 32-33 in a truck.

I've always run just a few pounds short of the max. The worst tire wear and deterioration occurs from underinflation, so I've always steered clear of it. 'Sides, you get better MPG with lower rolling resistance.

yeah but they max at 85 lbs and ride rough at 55 so i'm running 45lbs.

BFG's 315's and Im running 40psi
