That appears to be the case. For me they don’t make sense; I had three sets and they did not meet my expectations, but other tires do,so… I buy those instead. But maybe Michelin has its good points. Lots of stuff doesn’t “work” for me.Michelins are a use em or lose them kind of tire. I still buy them anyway, even knowing they will likely rot and be "wasted" years later. I'l pay for the performance and ride quality.
