Tire brands and warranties

I'm not a fan. Here's why. Michelin makes a great tire. Too good. The tread lasts too long. They usually separate and blow out before they wear out. I want a tire whose tread does not last that long. Michelins become unsafe after many years on the road. I am proof positive. My Ford truck had Michelin tires on it when I bought it. I knew they were old. They were checked on the sidewall. I should have replaced them when I bought it. I didn't. Mother's Day 2015 I had a severe blowout on the left front that dragged me across the oncoming lane all the way onto the opposite shoulder of the road. I was only going about 45. Had someone been coming the other way, it would have been bad.

As stupid as it sounds, I won't buy Michelin tires because the last too long. They actually outlast the longevity of the tire's construction. I've seen it a lot in the past being in the tire business before. If you run Michelin tires, keep a close watch on them.
Back when I was manager of a Consumer Tire shop in Hawaii we used to say that Michelin was a French word meaning “exploding tire”.

It was the same issue you described. They put on very few miles on the Island so the long treadlife meant people kept them on their cars for so long that they eventually failed catastrophically.
