From Wiki:
Following several tyre failures before the race, which caused major accidents for Ralf Schumacher's Toyota during Friday practice and Ricardo Zonta in the other Toyota, Michelin advised its seven customer teams that without a reduction in speed in Turn 13, the tyres provided for the race would only be safe for 10 laps. Michelin had been providing working tyres for the race since 2001. The situation was worsened by the 2005 Formula One rules, which forbade tyre changes during the race.
The Fédération Internationale de l'Automobile (FIA), the sport's governing body, refused a compromise proposal from Michelin to allow a chicane to be installed, maintaining that such rule changes would be grossly unfair to the Bridgestone-shod teams, who had come prepared with properly working tyres, and that a last-minute change to the track layout would be dangerous in case of crashes. The Michelin teams, unable to come to a compromise with the FIA, decided not to participate. It was later stated that the Michelin-shod teams could have potentially exposed themselves to criminal liability under Indiana state law had they competed.[2] It was also thought, since Bridgestone also provided tyres to the Indy Racing League via its Firestone brand, it understood better the loads the tyres would be under. Thus Bridgestone was able to provide a proper tyre.
In a letter to FIA Race Director Charlie Whiting dated Saturday, June 18, Michelin representatives Pierre Dupasquier and Nick Shorrock revealed that they did not know the cause of the Toyota tyre failures, and unless the cars could be slowed down in Turn 13, they could not guarantee the tyres' safety for more than 10 laps.[10] Whiting replied on Sunday, June 19, expressing his surprise that Michelin had not brought suitable tyres, suggesting that the teams should limit their drivers to the maximum safe speed specified by Michelin in Turn 13. He also addressed several solutions which had been proposed by the teams, insisting that use of the new specification tyres flown in overnight would be "a breach of the rules to be considered by the stewards", and the placement of a chicane in the turn was "out of the question" – the race would not be sanctioned by the FIA (making it a non-championship race) if the track layout was changed. He deemed the Michelin teams' proposals to be "grossly unfair" to the Bridgestone teams.[11][better source needed]
In a second letter, also dated June 18, Dupasquier and Shorrock confirmed that they would not permit their teams to race on the Michelin tyres used during qualification without changes to the circuit, and reiterated their request to slow down Turn 13. Whiting's brief reply maintained that no such change would be permitted, and gave the teams the choice of limiting speeds through Turn 13, using tyres of a different specification to those used in qualifying, subject to a penalty, or changing tyres repeatedly, which would have been permitted if a driver's safety were at issue
The Michelin representatives stated their position that the tyres provided to the teams could not safely complete the race distance, and requested that the Bridgestone teams, represented by Stoddart and Jordan's Colin Kolles, permit the installation of a chicane in Turn 13. Those present discussed and agreed to reject the FIA's solution of speed-limiting the Michelin cars in the turn because of the potential for accidents. They likewise dismissed the possibility of making pit stops every ten laps, resolved that a chicane was the best solution, and instructed several technical representatives to prepare plans for its installation. Bernie Ecclestone volunteered to consult Todt, who had not come to the meeting, and the president of the FIA, Max Mosley, who was not present at the race, and reconvene the meeting when he had responses.[9]
Ecclestone returned at about 10:55 to inform the group that Todt had refused to agree to the chicane, maintaining that it was an FIA and a Michelin problem and not his. By the time Stoddart's account of the meeting was published, Todt had already denied that he had ever been consulted, but stated that, if asked, he would not have agreed to the chicane.[13] Furthermore, Ecclestone reported that Mosley had "stated that if any attempts were made to alter the circuit, he would cancel the Grand Prix forthwith".[
