Colour coded tyres for Formula One

6:35 am on 19 March 2011

New supplier Pirelli says Formula One tyres will be colour coded from next week's season-opener in Australia to help fans tell which of six kinds are being used by drivers.

The Italian company says that prominent logos on the sidewall of each tyre would carry distinct colouring depending on the type.

Only two of four possible compounds of slick tyre will be available in each race, plus intermediate and wet tyres in the event of rain.

Pirelli says the wets used in heavy rain conditions would be coded orange while intermediates suited to a damp and drying track would be light blue.

Supersoft compounds, providing speed at the expense of durability, will be coded red.

Soft tyres that last slightly longer will be yellow, medium tyres white and hards -- the most durable of all -- silver.

Pirelli have replaced Bridgestone as sole supplier, with tyres expected to be less durable and play a bigger part in race strategy by also increasing the amount of overtaking and producing more pitstops.
