Time to buy tires

When I bought my coach used, I wanted to replace all the tires. I consulted with a friend who had just sold all FIVE of his Goodyear stores. His advice, based upon years of selling various brands and monitoring tire failures was " I would not consider any tire except Michelin for a coach. Michelin simply makes a stronger, safer tire and I saw much fewer tire failures". We travel backroads in the mountains a lot. I want to decrease as much as possible the chance of tire failure on one of those narrow curving roads. I am getting ready to put my second set of Michelins on after five years. To me, the extra confidence I get with Michelins, whether real or imagined is worth the extra money.
