Pirelli have introduced 4 new tyre compositions

Following the first look at the Caterham CT01, Pirelli have also revealed the rubber that all 12 F1 teams will be running on this season.

The Italian manufacturer has constructed brand-new soft, medium and hard compound tyres, with the super-soft formula being carried on from last year. There is also a new extreme wet tyre to be used.

The new tyres will be of a softer composition compared to last year.

The colour coding for the dry tyres remains roughly the same, except the hard tyre is now a much lighter silver colour, and it is expected to be almost invisible at high speed.

The intermediate tyre is now coloured green, while the new extreme wet compound is blue.

All 6 variants of tyre contain slightly wider contact patch than 2011, to counteract the loss of downforce from the banning of off-throttle diffusers. Pirelli explained that they have incorporated less of a rounded shoulder on the rubber to improve grip.

They also noted that they intend to reduce the performance gap between the options and primes on race weekends, from 1.2-1.8 seconds last year to around 0.6-0.8 in 2012.
