New tyre rule is a pain

on

A new regulation in Formula One is a 'pain in the neck' for Michelin. Partner teams must select a single tyre-compound for the whole weekend right after Friday morning practice, to ensure they maximise allowed track-time. Dupasquier added that with so little time, the teams will have to make a decision from a pool of data from all teams, rather than based on science.

It will involve 'theoretical judgements,' said the French motorsport boss, despite the many millions of dollars that Michelin plough into the category. 'On the one hand it's quite interesting,' he continued, 'but on the other we're spending so much but we're not allowed to generate that much useful data.'

Selection on Friday will also be difficult for other reasons, he explained. For example, 'on Friday the track is usually so dirty,' said Pierre.
