I had a set of Terra Grapplers with about 45k on them and had just purchased some new Dune Grapplers. I had them in the bed and went to my buddies work to have the new mounted. I pull up and he comes out with another guy asking "how much air do you run in the rears?" I tell him 55 and ask why, he says well me and Shawn were wondering, since you have new tires and all . . . I said "say no more. " And pulled along side the shop where there's about a 120' straight paved area. Spooled up, power breaking it, and letter rip the whole length, turned around and did it again. They were whoopin and hollerin so much I did it 2 more times. There must have been a half inch of rubber on the tail pipe and in the wheel well. I didn't have the lock rite in at the time so it was a peg leg show. I would have done it again but the boss came out and told them to have me stop before the fire trucks came thinking it was a fire. So I pull in the shop and after they get me settled in a bay I lift the hard ton-au cover to get the new rubber out and smoke just poured out of the bed. We all laughed some more - when we took the back tire off the tread was super flat with stones and god knows what embedded in the molten rubber. S'all Gud . . .
