In yesterday's warm-up, just prior to final qualifying Michael Schumacher posted the quickest time in 1’22”210. Therefore, when the Ferrari man was just about the only front runner not to go quicker in the one lap qualifying shoot-out, the Scuderia engineers were keen to find out why. Eventually, after lengthy analysis of all the car’s data, the fault was traced to the air pressure in the tyres. Before each run, tyre pressures are set to a formula which allows for them to warm up on the “out” lap from the pits, reaching optimum operating temperature at the start of the critical timed lap. On this occasion, Schumacher’s tyres took longer than expected to reach that correct temperature. This explains why the German complained of lack of grip. Eventually, through running and cornering forces, the temperatures did reach their optimum. That can be verified from the fact Michael’s times over the final sections improved to the expected level. Of course, this does not alter the fact that he starts from eighth on the grid, but at least the team now has an understanding of what exactly caused the problem.
