What are the tyre compounds in F1?

Tyre summary

Do you have to use 2 tyre compounds in F1?

Cars must race on any 2 dry compounds during a race unless intermediate or wet tyres have been used by that car in that race. Starting the race behind the safety car due to heavy rain requires cars to be fitted with wet tyres until they make a pit stop. Heaters may be applied only to the outside of tyres.

Which tyre compound is fastest?

C1 Compound: The C1 compound is the hardest tyre in the 2021 tyre range. This tyre is specifically designed for circuits that have fast corners. These tyres are for the tracks that put the highest loading through these tyres, typically abrasive surfaces with a high ambient temperature.

What happens to tyres after F1 race?

All of the tyres are transported back to Pirelli’s engineering and logistics hub at Didcot after each race weekend, where they are finely shredded, along with other road car tyres. The shredded tyres form small pellets, which are then burnt at extremely high temperatures as fuel for cement factories.

How many tyre compounds are there in F1?

Last season, there were seven different tyre compounds (plus two for wet weather conditions) — from hypersoft to superhard — with seemingly all the colors of the rainbow to differentiate! This year, color range is reduced from seven to just three.

When did Bridgestone become sole tyre supplier in Formula One?

Tyre changes were re-instated in 2006, following the dramatic and highly political 2005 United States Grand Prix . For 2007, Bridgestone became the sole tyre supplier in Formula One with the withdrawal of Michelin, and introduced four compounds of tyre, two of which are made available at each race.

Why are the sidewalls of Formula One tyres green?

Upon the reintroduction of slicks in 2009, the sidewalls of the softer tyres were painted green to indicate the difference in compound, as there were no longer any grooves in tyres. Each team must use each specification during the race, unless wet or intermediate tyres are used during the race, in which case this rule no longer applies.

What does C2 stand for in F1 tires?

C2 means Compound 2, which is a very versatile compound that sits at the harder end of the spectrum. It comes into its own on circuits that tend towards high speeds, temperatures, and energy loadings. This tire has demonstrated an ample working range and adaptability to a wide variety of different circuits.
