At each race weekend, Pirelli will nominate three of its compounds to go to every race, based mostly on the circuit and its predicted ranges of degradation, usually choosing their softest compounds at avenue circuits similar to Monaco and Singapore, and their hardest at high-wear circuits like Suzuka and Silverstone.
The chosen F1 tyres are then marked into three classes:
Gentle (purple): The quickest tyre over one lap, however the least sturdy – finest for qualifying.
Medium (yellow): The ‘in-between’ tyre which balances pace and sturdiness, usually beneficial within the first stint of a race.
Laborious (white): Probably the most sturdy of the three out there compounds, although offering the least grip for single-lap tempo – finest for race technique choices.
Then, there are additionally two wet-weather tyre choices out there at each race weekend, and the softness of their compound doesn’t change all 12 months:
Intermediate: Partially grooved with tread to clear minor standing water and navigate a slippery monitor floor.
Moist: Marked with deeper tread to work within the hardest, wettest driving situations.

The groups should return two units after every free follow session, too – leaving seven out there in complete for qualifying and the race, one in all which being a set of soppy tyres they have to maintain to 1 aspect to be used in Q3.
Those that make it to Q3 should then return that set of soppy tyres, leaving six units for the race, whereas the underside 10 qualifiers can have that recent set of softs out there for the race, in the event that they select to make use of them.
4 units of intermediates and three units of wets are additionally out there to be used for every driver at each race weekend.
