At the last minute, the seven teams using Michelin tires did not show up to the starting grid of the US Grand Prix. This left only 2 teams sporting Bridgstone rubber to take part in the race. Below is the statement from Michelin.

"Michelin is very disappointed about the way the United States Grand Prix turned out at Indianapolis today, for the public, the drivers and the teams.

Michelin is sorry that the tyres it ran in free practice and qualifying were not suitable for use in racing conditions this weekend, but driver safety is always a priority. Michelin will never change its stance on this principle, whether we are talking about tyres for competition or any other purpose.

It is regrettable that our pre-race suggestions, agreed in conjunction with our partner teams, were not adopted. Had our ideas been followed, we could have guaranteed driver safety, the participation of our teams and added interest for the public.

Michelin would like to thank its seven partner teams for their close collaboration, for having made propositions to the FIA and for having respected our advice on safety issues.

Michelin will continue to investigate the technical reasons for the tyre-related incidents that affected Toyota during Friday’s free practice."
