Sof Supersoft and ultrasoft for Singapore

Pirelli, the sole tyre supplier to the Formula One World Championship, will be bring three tyre compounds to this weekend’s Singapore GP, the soft, supersoft and ultrasoft.

P Zero Yellow soft – less grip, less wear (used for long-race stints)
This is one of the most frequently used tires in Pirelli’s range, as it strikes a balance between performance and durability, with the accent on performance. It is still geared toward speed rather than long distances, but it remains capable of providing teams with a competitive advantage at the beginning of the race where cars are carrying a full fuel load, and at the end of the race where the fuel load is much lighter and the race effectively becomes a sprint. It is a high working-range compound.

P Zero Red supersoft – more grip, medium wear (used for shorter-race stints and for initial portion of qualifying)
This is the second softest tire in Pirelli’s range, and it is ideal for tight and twisting circuits, especially in cold weather, when maximum grip is needed. The supersofts warm up rapidly, which has made it a stalwart choice for qualifying. But with increased grip comes increased degradation. It is a low working-range compound.

P Zero Purple ultrasoft – highest amount of grip, highest amount of wear (used for qualifying and select race situations)
This is the softest tire in Pirelli’s range, with rapid warming and massive performance. It is best used on tight and twisting circuits that put a premium on mechanical grip. However, because it is so soft, it has a limited lifespan. It is a low working-range compound.

The Singapore Grand Prix marks the seventh time these three compounds have been packaged together. Teams most recently used this tire package in the Belgian Grand Prix Aug. 25-27 at Circuit de Spa-Francorchamps. This is the same lineup Pirelli used for last year’s Singapore Grand Prix.

The Yellow soft tire has been used in every grand prix this season. The Red supersoft tire has been used everywhere except the Spanish Grand Prix. The Purple ultrasoft has been used in the Australian Grand Prix, the Russian Grand Prix, the Monaco Grand Prix, the Canadian Grand Prix, the Austrian Grand Prix and the Belgian Grand Prix.
