Well, now I need to know what's the best tire pressure for highway use.
I did the calculation - for the weight of my Wrangler and the new tires, I came up with 27-28 psi, which seems very low (and, in fact, at the current COLD 30psi, the bottom of the tire looks too bulgy to my untrained eye).
I think I'm going to try the chalk method tomorrow. Do any of you believe in the chalk method? It's to be done with warm, recently-driven tires, right?
I've heard it's "lower psi for off-road" to give better grip on gravel and dirt; "higher psi for highway and city streets." But higher or lower than what? Max cold pressure is 50psi for the BFGs - but I know you're not supposed to run at the max, especially when you're not carrying or towing any extra weight.
So, tire pressure anyone?
