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. It was also thought that since Bridgestone also provided tyres to the two Indy Racing League series (IndyCar Series and Infiniti Pro Series) via its Firestone brand, and had encountered issues during testing that caused them to return with different IndyCar tyres, it understood better the loads the Formula One tyres would be under. Thus, Bridgestone was able to provide a safe tyre.
