In 2005, there was a big problem with some of the Formula One tires. During practice, there was a big crash at turn 13. This part of the F1 circuit is the turn 1 of the oval track. This is also the only banked corner on the F1 calendar. Michelin realized their tires could not handle the banking. They would fail after a few laps. The cars using Bridgestone tires did not have the problem.
