I dont think the duratracs have been around long enough to find out if they last that long, but i highly doubt it.
BFG ATs can last very long if well taken care of or not long at all. it all depends on the vehicle they are on, the condition of that vehicle and the driving style. So many factors come in to play but they can last a long time.
