Does anyone know if the sidewall condition is an issue?
Michelin published a wallet card that showed the crazing and how deep the cracks could be before it was considered dangerous. Somehow I misplaced all of them. But here's what they now publish:
"If the cracks are less than 1/32" deep the tire is fine to run. Between 1/32" and 2/32" the tire is suspect and should be examined by your Michelin dealer. If the cracks are any deeper than 2/32" (1/16") the tire should be replaced immediately"
This is the same as the card showed and stated so it hasn't changed. If it's just surface crazing then it's not a problem. Any tire needs to be run to keep the oils moving to the surface. Our OEM Michelins went over 8 years and still hadn't reached the 2/32" point. But I did replace them anyway.
