I also had a puncture but due to a big screw. The tire shop looked at it and advised me to replace it because of the location of the puncture being too close to the sidewall. There is a separate thread on this. Since the tire was OEM Michelin RFT, I believe Michelin will cover part of the cost of the tire. The case is still open. The tire shop went ahead and replaced the tire. They are working directly with Michelin. I haven't paid anything so far. I will report when I know more.
