Wasn't the situation somewhat different?
It sounds like the NASCAR tires were wearing out, but my understanding with F1 was that the Michelin tires were failing unpredictably due to the unusually high forces and high speeds around the sectio of banking. It's one thing to have to change tires every 10-15 laps because they're wearing out, but quite another to have a tire fail without warning and put you into a concrete wall at 200mph. Basically the F1 teams on Michelin tires were advised by Michelin not to run as they were not confident that the tires would be safe.
