275/80r 22.5 tires

First of all if you want to run those slightly used 7 year old tires I would take them to a tire shop and have them broke down (off the rim) and inspected inside and out that way you know what you have. I'm on my second set of XRV's having run my first set for 10 years. In the 10th year of the mentioned set I got minor UV cracks on the sidewall. This was my fault due to I didn't cover my tires from the Arizona sun. You can go to Michelins Quality Care Website and no where on that website does it say you can run on cracked tires. But, it does say the cracks can be run on, if there within a certain depth and they are Inspected by a tire expert (Not a RV.Net tire expert). I have never had a Michelin Tire blow out on me in my RV or my Semi truck in over 44 years! Is that coincidence I don't think so! My life depended on a lot of different Michelin front end steer tires in the millions of miles that I drove OTR (Over the Road). The Michelin XRV is a true soft rubber RV tire designed for RV applications only (RV's sit a lot without moving this is just one of the many applications) XRV are not hard rubber truck tires that the Michelin bashers always fail to mention! I like Pastor Charlie, purchased my tires from the FMCA/Michelin Fleet Tire Program at a discount for $378.00 per tire my local Michelin Dealer wanted $505.00 per tire plus freight! Do your homework when buying tires! Good Luck
