I'm running Good Year Duratrac's 285 75 16 and was hoping to get some help on what pressure I should have in my tires. If it matters, 2 door JK Sport.
Even at optimal pressure you may not get the chalk to rub off on the outer edges depending on wheel width, etc. It should still give you a pretty good idea of how much pressure will allow the most tire possible touching pavement without being under inflated
