Hmmm sorry to be a downer, but I've had two irreparable in 30000. One had a sidewall tear on a rocky section of road. Fair enough, but a bit dissapointing I thought, given the big sell on the LT construction and strong sidewalls.
Second one lost a tread block. YES a tread block on an AT. This was during a long outback trip towing my van. Bridgestone would not warranty it, which I thought was very poor. It was deemed wear and tear.
Road noise is low though.
So all in all for me , never again. I'll be back to either a Mickey or a BFG
