The new rules in formula 1 state that only one set of tires are allowed for bit qualifying and the race itself. which so far this season hasn't caused many headaches. However, this year at Indianapolis on turn 13 where the cars reach nearly 300kph (on the bank clockwise befor the start/finish) Michelin's tyres are unable to cope with the high stress loads. As a result, 13 teams have pulled out, leaving Jordan, Minardi and Ferrari as the only racing teams. What an absoloute farce.
