First filed 19 March.
Ahead of next this weekend’s Australian Grand Prix the sport’s new new tyre supplier Pirelli has announced it will use coloured labelling on the sidewalls to differentiate between its different tyres during the 2011 Formula One season.
At each Grand Prix four types of tyres will be available; wets, intermediates, primes and options. The prime and option tyres are slicks and will be nominated before every race from a range four different compounds; supersoft, soft, medium and hard.
For example, the first three Grands Prix this year—Australia, Malaysia and China—will use the hard compound for the prime tyres and the soft compound as the options.
A total of six colours will be used to tell each tyre apart:
- Wet – orange
- Intermediate – light blue
- Supersoft – red
- Soft – yellow
- Medium – white
- Hard – silver
To begin with Pirelli wants to have at least one full step between the prime and option tyres. Meaning teams would not have the choice between the supersoft and soft at the same race.
