Careful management of his car's tyres helped McClaren's Jenson Button secure his second victory of the F1 season at this weekend's dramatic Belgian GP.
The race got off to a tumultuous start as aggressive driving from Romain Grosjean caused a six car pile-up in the opening seconds. Grosjean swerved into Lewis Hamilton, removing both him and championship leader Fernando Alonso from the race in a spectacular and dangerous fashion.
With the fight for pole position thrown open, Button opted for a clear tyre strategy, managing this season's fast-degrading Pirellis artfully to take a comfortable victory.
Starting with the P Zero White medium tyres, the British Ace made one pitstop on lap 20 to switch to the P Zero Silver hard tyre.
The pile-up at the start of the race brought out the safety cars for four laps to clear debris, allowing drivers to alter their tyres strategy as speeds slowed.
Paul Hembery, motorsport director at Pirelli, admitted that this year's Spa race "placed heavier demands on the tyres that any other circuit on the calendar".
"Jenson Button and McLaren gave us a master class in tyre management, stopping just once but at the same time pulling away from their rivals," he said.
