DISCOVER ALL TYRES RANGE
C1 stands for Compound 1, and it is the hardest tyre in the 2021 Pirelli range. It is designed for circuits that put the highest energy loadings through the tyres, which will typically feature fast corners, abrasive surfaces, or high ambient temperatures. The compound takes longer to warm up but offers maximum durability and provides low degradation.
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 tyre has demonstrated an ample working range and adaptability to a wide variety of different circuits.
C3, or Compound 3, strikes a very good balance between performance and durability, with the accent on performance. It is a very adaptable tyre that can be used as the softest compound at a high-severity track as well as the hardest compound at a low-severity track or street circuit. It is one of the most commonly used compounds of all.
C4 – Compound 4 – works well on tight and twisty circuits. It has a rapid warm-up and huge peak performance, but the other side of this is its relatively limited overall life. However, the improved consistency of this year’s compounds should mean that the softer rubber is capable of more versatile use and less prone to overheating.
C5, which stands for Compound 5, is the heir to the universally-popular hyper-soft: the fastest compound that Pirelli has ever made. This tyre is suitable for all circuits that demand high levels of mechanical grip, but the trade-off for this extra speed and adhesion is a considerably shorter lifespan than the other tyres in the range. It is not a qualifying tyre, but it comes closest.
The intermediates are the most versatile of the rain tyres. They can be used on a wet track with no standing water, as well as a drying surface. This tyre evacuates 30 litres of water per second per tyre at 300kph. There’s a new compound that is designed to expand the working range, guaranteeing a proper crossover both with the slicks and the full wets.
