I can't get more than 25-30k miles out of a set, however they're on a 3/4ton diesel pickup pushing 500hp 800 ft lbs.I have B.F. Goodrich AT/KO's on my Dodge Ram 4x4, they are excellent in every way. My friend who is a manager at a Discount Tire says that the rubber compound has been changed and the quality is no longer the same. He now prefers the Yokohama brand, but I do not recall which model specifically.
