I have no idea how they wear, but considering there for a 10,000 lb military tuck id say pretty good probably, ive only got 10 or 15 miles on them. They howl like a mutha fukka, and i got them cheap, like 6 for $700 canadian, but they were blems, and i bought them second hand, but they were still new. New they list for $650 CND a piece which believe it or not, is about the price of a similar size bogger, when shipped here. They are one awsome mud tire though, dig right down and clean out easily, with little wheelspin. I would get another set if a i had the chance.
