Williams calls for 2011 tyres test

Sam MichaelFormula 1 teams should be granted a special post-grand prix test session after one of this season's races to help them get an understanding of next year's tyres.

That is the view of Williams technical director Sam Michael, who thinks that the best solution for helping teams better understand tyre characteristics for their 2011 car designs is to give them a day's running with the new tyre supplier.

F1 teams are hoping to finalise whether they want Pirelli or Michelin for next year before the Turkish Grand Prix - although teams already have to get on with their 2011 designs without knowing who will supply tyres.

Michael reckons that even with full data from F1's new tyre supplier it will be hard for teams to fully understand how the rubber will behave.

"We have to just crack on with the design, assuming the tyres are similar to what we have got now because we don't have any other data," Michael told AUTOSPORT.

"We haven't decided on the tyre supplier, and even when you get the data it will be hard to ascertain the differences between Bridgestone and whoever it is without running the car on track. Hopefully we will have some sort of test.

"I think the ideal thing would be to stay back after one or two grands prix, maybe stay back on the Monday after Monza or Abu Dhabi, and do two one-hour practice sessions with a couple of sets of the new tyres if they can be produced that quickly."

Abu Dhabi is already in talks with F1 teams about holding a test immediately after the season finale, possibly for the young driver running that is currently allowed in the regulations.
