I'm going to get about 35K out of mine w/camper weight 24/7. I bought them mounted on stock rims @ 19,000K from a friend who never rotated nor rebalanced them. They carried his truck and camper also. They're right at 29,000 now and looks like in about 5-6K more they'll be ready for replacement. I'm going to replace them with another set of Toyo 285-75-17 AT's. BTW,no flats,cuts,nada.
