Yeah, you may have had a puncture, or loose valve stem, then ran it until it shredded. I had about 8 massive blowouts with Goodyear tires before I finally got wise and switched to the Michelins. We never missed a Goodyear blowout; it sounded like a stick of dynamite went off beside the road and rubber bits went everywhere; no one ever had to tell us. I've been using those same Michelins for about 10 years now and never a problem, not even a flat; except one time in the trailer shed when I had a loose valve stem and it went flat.
