This season the performance of the Pirelli tyres is going to be a real talking point and absolutely central to the outcome of races.
In order to help the fans, journalists and TV commentators identify which tyre is which they have colour coded the tyres for quick and easy identification.
This will be useful in qualifying, to see whether anyone feels they can get through Q1 on a set of hard tyres (the difference is said to be as much as 1.5 secs on a lap between soft and hard) and in the race to see what tyres a driver puts on at the pit stops.
In the slick tyre range, for dry weather running, the silver tyre (right of picture) is the Hard, the White tyre is the medium the Yellow is soft and the Red is supersoft. These should be very easy to spot during the practice, qualifying and race on TV and in the grandstands.
You will be seeing the Silver (hard) and Yellow (soft) in Australia next week and at the next two races in Malaysia and China.
