Michlin WAS given the option to change tires during the race. They refused it because of the loss of track position the extra stops would make. They wanted to have their cake and eat it too. None of the Michlin teams had a problem with the rules when they had an advantage as a result of them.
Here's what I've been able to put together from bits and pieces.
My Trek friend was at a presentation with Michael Saturday night. He told me Michlin had flown in tires and wanted to change them. They were told "not unless the Bridgestone runners can change too".
Ron Dennis said, in a SPEED channel interview that Michlin had found out at 5:00 AM Sunday that the replacement tires had the same problem.
Bob Varsha read a letter from Charley Whiting telling Michlin that they were required to provide "adiquate back-up" tires which they had not done. That changing the course to give a manufacturer who had "inadiquate equipment" a competitive advantage was grossly unfair to those who had brought adaquate equipment.
According to Peter Windsor, on Windtunnel, Michlin had a chance to test tires at IMS but only sent one minor team's Friday driver. The rest went to Silverstone. "Had they done the testing, they would have been aware that there was a problem from the "Diamond Grind" on the oval's surface". Brigestone could have recieved that info from their Firestone division when they tested IRL tires. In Peter's opinion Michlin's claim of "safety" was a sketchy judgement call on their part to save face.
According to Jean Todt, on F-1 Live, he was never consulted and didn't protest.
Also according to articles in F-1 Live:
Michlin was given, and refused, the option of changing tires during the race.
They could have reduced speed in that corner.(they refused this unless the Bridgestone cars would also do the same)
The FIA said changing the course would void it's sanction (just like in skiing)
Michlin had recieved a letter two weeks earlier not to compromise safety on their tires.
Ferrari didn't ask for a rules change after Michael flatted two tires and withdrew from a race.
Adding a chicane on Sunday would have been like changing a gate in the Hanninkamm after the fore runners had gone.
Isn't this about technology? Michlin didn't have it so they took their "ball" and went home.
What we used to say in drag racing, "Run What Ya Brung and hope ya brung enough" (Michlin obviously didn't)
Michlin has won every race this year. When they get caught with their pants down they refuse to race unless they can have some kind of rule change to their advantage. That sucks
I paid $95 for seats one row from the top in Northwest Vista (turn 4 of the oval) I'm pretty bummed
Having heard the FIA's case, and based on my experience as a TD, I agree with them completely. This is Michlin's fault and F-1's version of CART vs IRL. Look what happens when a bunch of team owners try to make rules and run a series. There needs to be a "governing body"
