MILAN (REUTERS) - Pirelli presented its 2013 range of colour-coded Formula One tyres on Wednesday with the hope that fans would see more overtaking and an end to one-stop races.

The Italian company's range of tyres has undergone a revolution with new structures and new compounds aimed at producing more exciting racing and ensuring at least two stops per driver in every race.

Last season started with an unprecedented seven different winners in the first seven grands prix but the racing became more predictable as teams understood the tyres better.

The P Zero range of dry weather tyres are faster by up to 0.5 seconds a lap and the performance gap between the compounds is also at least half a second in order to enhance race strategy and differences in speeds during the race.

The sidewalls will have new markings, with orange now denoting the hardest compound instead of the silver that was used last year.

Pirelli said the new hard tyre would be roughly equivalent to last year's medium compound, with softer sidewalls but stronger shoulders.

Improved traction, especially on the exit of corners, should translate into faster lap times.
