Dangerous for use on track
I have OEM Michelin Run Flats Sport Cup 4S on my Corvette C8. Regular driving these are fine. They are DANGEROUS for track use though. These tires are UNSAFE and have batch defects in my opinion and people should be informed before someone gets hurt. I followed Chevrolet's track prep guide for the car (that says this tire can be sued on track). I have been on tracks for 15 years and have never had tires delaminate like these and fall apart after 1 session of a track day. I called Michelin and there customer service tech said it wasn't a defect or covered. He pretty much said it was my fault and never even made the time to look at the images I had. Michelin did not stand behind their product. I will NEVER buy a Michelin tire again. Sad.
