Michelin are continuing their search for the cause of Toyota’s two Friday tyre failures at Indianapolis. In the meantime, what tyres the Michelin teams will use in the US Grand Prix remains unclear.

"As previously explained we are still continuing our investigations into yesterday's tyre incidents,” confirmed Nick Shorrock, Director of Michelin F1 activities, after Toyota clinched pole position at Indianapolis.

“This consists of full examinations of all the tyres that ran on Friday and those from Saturday morning's free practice sessions. In addition we are continuing to work at our research centres in Clermont-Ferrand and Greenville, South Carolina. As yet we have not been able to understand the reason leading to yesterday's sudden tyre-pressure drop on two Toyotas.”

Unless Michelin can locate the problem - and come up with a solution that falls within the regulations - they will not recommend racing with the tyres used in qualifying, although the teams are not obliged to follow any such advice.

"During the build-up to the United States Grand Prix, engineers at our research centres will continue to focus on the product we ran today to decide if we will be able to use this specification safely in tomorrow's race," said Shorrock.

If Michelin decide they cannot be used safely, their teams could face a major dilemma. A new batch of tyres is being flown in from France, but in using these competitors would be breaking several Formula One regulations.

Meetings are taking place between the parties concerned to try and reach a solution, but a final decision is thought unlikely before Sunday morning.
