Bought my Chevy truck with these on fairly new, never seen them before. In awe at how much pounding they took. I was hitting curbs, driving over ugly looking rocks and the tires had no problems. The tires are 6+ years old and I've done 3kkm road trips with no problems. For this alone I am getting another set. Alas I managed to drive straight over a bottle and get a nasty puncture, which while mended makes me think the tires are getting old enough to swap.
