The 2009 Formula One season will conclude this weekend at the Yas Marina Circuit in Abu Dhabi (yes, I too had to look it up.) But with Jensen Button
already wrapping up the Drivers' Championship in Brazil on October 18, and the Constructors Championship already awarded to Brawn GP, this last race of the
season loses at least some of its excitement.
Button and his F1 colleagues rely on many vehicle components to carry them to victory each race weekend. The main performance areas of the car include
engine, aerodynamics, and chassis dynamics. But perhaps the biggest contributor to quick lap times is the tires.
Although each of the ten entrants must build their own chassis and there are only five engine suppliers, there is but a single tire supplier: Bridgestone.
So although tires may be the most important performance component, at least each F1 entrant is on equal footing for this parameter.
2009 saw the return of slick tires in F1 after 10 seasons on grooved tires. Teams have a choice of three types of tires depending on weather conditions:
dry slick, intermediate, and wet. There are two specifications of dry slicks at each event, one intermediate specification, and one wet tire.
