Glad you or anyone else weren't hurt!!!!
It doesn't seem to be any particular brand of tire that blows out more frequently than another. At least from what I've read on here anyway. I've had two Goodyears fail fo rme and I'm still running them. The first was an old tire (10 years plus) that I didn't verify the dates on when we bought the coach. My fault. The second was a brand new G645 that the tread just came off....peeled right off like an orange peel. Goodyear made it right with my insurance company, and I'm still running the brand. As noted above, I've seen reports of Michelins blowing while sitting still. I read reports that Michelins are notorious for sidewall cracking after a couple of years. Lots of other folks run other brands and have had problems with them. It usually boils down to how they tires are maintained and their inflation condition at the time of the blowout. I honestly don't think, again, that there is one tire more prone to failure than another. My $0.02 worth.....
