The rules banning tyre changes during the race were introduced as a cost cutting measure and Michelin are very critical of the latest changes.
Michelin stated that the new regulations means a completely new tyreThis urgent change, without advance notice:
Is incoherent with the cost reduction objectives sought by the FIA President
Is a step backwards in regards to the 2005 regulations presented, at the time, by the FIA solely for cost reduction purposes.
As a result, these new rules will immediately increase tyre development, production and logistics costs by 15% since, contrary to what has been said, the 2005 solutions can by no means be adapted to the new 2006 regulation.
Michelin questioned the hidden motives of the FIA and accused them of lack of transparency and incoherent decision making.Tyre wear and grip are calculated to ensure an optimum performance for a specific distance. To switch from a tyre designed to run for 350 kms in 2005 to a tyre that can be changed every 100 kms (or less) in 2006 will require tyre manufacturers to design an entirely new generation of tyres and will therefore increase costs
Full Michelin Statement - 2006 F1 Regulations ThreadWe can only question the meaning behind this decision which negates all of the benefits of Michelin?s research in 2005 to design a tyre capable of running for 350 kms, allowing its partners to win 18 races throughout the year.
Michelin, therefore, questions the FIA's hidden motivations for the 2006 F1 regulation.
Once again, this event illustrates the F1?s problems of incoherent decision-making and lack of transparency.
