The United States Grand Prix
Ferrari's Michael Schumacher (right) stays on the track as the Michelin users file into the pits before the start of the race.
All seven of the teams supplied by Michelin, including championship front-runners Renault and McLaren, formed up on the grid, but were back in the pits at the end of the warm-up lap.
