I had 3 Michelin XRV blowouts on our motorhome and Michelin denied any responsibility for the problem. The weight was verified as UNDER the tire capacity. The pressure was certified by the dealer, the day before one of the blowouts, but according to Michelin, it was my fault. Instead of calling out someone, do a simple internet search of Michelin problems and spend the next week reading. Premature sidewall cracking, zipper blowouts, etc. It is all there for your reading.
