Michelin Comments On Rossi's Tire

On lap 16 of last month's Shanghai GP, Valentino Rossi had to pit due to excessive vibration from his front tire, which was found to have been caused by the loss of a small piece of tread. The tire remained inflated despite the missing piece of tread.

The analyses conducted at Michelin's Clermont-Ferrand HQ did not show any fault in the tire. The same tire specification was used by seven other Michelin riders in the same race without any trouble throughout the 22 laps.

The very high level of stress experienced at Shanghai by the center part of the tire is the highest during the whole MotoGP season, because of frequent decelerations from over 320km/h to 60km/h within less than eight seconds. It would appear that this tire could not sustain that level of strain; the safety margin we always include when we develop a tire was apparently not enough in this particular case. The parameters that influence the levels of stress that a tire undergoes are, among others: track layout, grip level, riding style and bike setup.

We apologize wholeheartedly to Valentino and the Yamaha team for having failed in this case to provide a front tire capable of being competitive throughout the race. We have, of course, already taken all necessary measures, where physically possible, to ensure that such an event doesn't happen again.
