WTF?
What the Michelin teams have decided they aren't racing or what?
Probably stuned.
The French company wanted changes made to the track at the very last minute. Made the claim late last night. Remember the next time you tire shop.
Michelin tires are having problems with turn 13 (big right hand just before finish). It's where Schumacher crashed last year and this year's qualifying.
Michelin and teams asked for a chicane to be placed there to slow all the cars down to reduce downforce/tire loading. F1A refused (max Mosely's decision). Michelin wouldn't certify their tires for the race.
Teams won't race on uncertified tires because of driver danger and lawsuits/etc. They pulled out for driver safety concerns.
