"Michelin have issued set up details, involving camber angles and tyre pressures, to all of their partner teams, but wish to fly in a new specification of tyre for the race tomorrow.

The FIA is unlikely to allow this on the grounds that it would contravene no fewer than four regulations: A different actual tyre; a different specification of tyre; more than the allowed number of sets per weekend and non-nomination of tyre prior to Saturday a.m."

"To fly the tyres to Indianapolis would take around six to seven hours and realistically they cannot be in Indiana before the morning. Thus if the Michelin teams were to run the tyres on race day, they would be breaking the rules and it would be up to the stewards of the meeting to decide on whether or not to impose a penalty. But penalising teams for doing something in the interests of safety is a situation in which the FIA will not want to put itself. However, one can see a situation in which the Bridgestone teams, namely Ferrari, will try to gain an advantage to pick up World Championship points. Responding to that, voices in the paddock say that if there is a protest from Ferrari, the other teams will simply not run on Sunday and so the United States Grand Prix would feature six cars: two Ferraris, two Jordans and two Minardis. That would be disastrous from a marketing point of view and the only obvious solution to the problem is to invoke force majeure rules and allow the new tyres to be run and a full field to be seen in action. Bridgestone would still be at an advantage because of the late arrival of tyres but there may then be questions about whether it is safe for the teams to go into a race on tyres that have not been used at all. Thus it might be necessary to have a short session on Sunday morning. But if that happens it is not clear how it could be handled under the parc ferme regulations that exist."
