The main difference with the XRV is the additional chemicals Michelin adds to the tire components that prolong the tire's life. This may be of value to owners who do not maintain tires properly. If tire maintenance is performed (clean, dressed, covered and proper PSI) any of the tires, mentioned in my post, will have outstanding performance on a motor coach. My tires are replaced every 10 years (unless there is a road hazard problem).
