I blew 6, of 6 total, tires going to the Ohio Mile and back last weekend. 225/75/15 Gladiator ST's. They were a couple years old, low miles though, maybe a couple thousand total.
Blew 4 on the way up there, and the remaining 2 on the way back.
Heading to Bonneville in 2 weeks, so I just bought a full set of Maxxis M8008's after doing some digging around/research. I bought new wheels to so I could go with the 16" tire which has an additional 600lbs weight capacity per tire. 235/80/16's.
Hoping for much better trailer time to Bonneville and back... that was ridiculous last weekend! (did get to go over 200 though, so the trailer pain is a distant memory)
