Pirelli reveals tyre colours for 2011 Formula One season

Pirelli has finally confirmed it will use different colours to visibly differentiate its tyre compounds this season.

We reported in January that the 'Pirelli P Zero' lettering on the sidewall will have a different colour per compound for the benefit of the spectators in 2011.
The Italian marque announced to the media on Friday that the hard tyre lettering will be silver, white for the medium, yellow for the softs and red for the super-soft.

The intermediate tyre letting is light blue, and orange for the full wet.

"These (colours) will enable both live and television audiences to tell at a glance who is on what compounds, which will be vital knowledge as tyres are set to form a key part of race strategy this year," said Paul Hembery.

The silver (hard) and yellow (soft) tyres will be seen at the first three grands prix of the year, starting with the season opener in Australia next weekend.

  • The dry tyres have a diameter of 660 millimetres. The tread is 245 millimetres wide at the front and 325 millimetres wide at the back.
  • The wet tyres have a bigger diameter of 670 millimetres, to raise the car and avoid standing water. The tread is 225 millimetres wide at the front and 325 millimetres wide at the back.
  • The diameter of the intermediate tyre is slightly smaller at 665 millimetres, although the same tread widths as the wet tyre apply.
  • A wet Pirelli tyre will disperse more than 60 litres of water per second when travelling at 300kph.
  • Pirelli will produce 50,000 Formula 1 tyres over the course of the season, bringing around 1,800 tyres to every race.
  • All the tyres are made in Pirelli's state of the art motorsport facility at Izmit, Turkey, just outside Istanbul.
  • At races, Pirelli will use 15 trucks and employ around 50 people, including one engineer allocated to every team.
  • Each front tyre weighs around nine kilograms. The rears, being larger, are a little heavier.
  • The operating temperature of each tyre is in the region of 90 degrees Celsius. The harder the tyre compound, the longer it takes to reach peak operating temperature.
