The Michelin tire Company is the creator of radial tires and changed the way tires are made for the world of tires. They are not exactly dummies.
Some of you are forgetting or are not aware that the Indianapolis Motor Speedway made one important change to the track in 2005... they made grooves in the surface between turn 12 and 13. These grooves created additional stress for tire walls never accounted for in F1 race tracks anywhere in the world in the history of F1 racing.
Firestone supplied tires to participants of the Indy 500. They build some expertise on the grooved surface of that particular corner and remember that Firestone is owned by Bridgestone, tire supplier for Ferrari, Jordan and Minardi. So, is anybody here suggesting that Bridgestone was as unprepared as Michelin to tackle surface grooves never before used on a F1 racetrack?
The FIA made an inspection of the circuit prior to the race ( as required under the rules) and I wonder how much importance did the FIA give and if they reported at all to the teams and the tire companies on the existence of these new grooves...
Whoever said the best team won is not following F1 racing this year. This was Ferrari's first win of the year.
Who was at fault Sunday? FIA has called the seven teams using Michelin Tires before the FIA Council on June 29 with specific accusations. See:

I am not impressed with the FIA handling of the whole affair.
