Italian tire manufacturer and official F1 supplier Pirelli for this season have announced a complete schedule of tire components to be used each weekend to make the job easier for both themselves and teams who will know in advance which components to use in which race.
Most of the components are similar to those for 2020 and 2019, but the tire selection for Baku and Interlagos is softer than before while the two races in the Netherlands and Saudi Arabia are brand new. The 2021 Sports Regulations have changed in terms of tire selection to provide maximum flexibility, and tire selections no longer have to be announced 14 weeks in advance for races outside Europe and eight weeks before races in Europe.
Also, as last year, drivers will no longer be able to choose the number of sets of each component they want to use during each weekend - each driver will receive two sets of hard tires, three sets of a medium, and eight sets of soft.
Pirelli and the FIA still reserve the right to change the choice of tires up to 15 days before the race if circumstances so require.
Pirelli helped Formula 1
For this season, Pirelli has prepared a firmer and slightly heavier tire construction that should reduce overheating and allow drivers to drive more aggressively, but that comes at a cost of about a second slower lap times.
Pirelli sought to help Formula 1 with the publication of tires for the whole year. They are aware of the situation around the pandemic and how much things can change in a second, so they tried to help Formula 1 in these difficult times.
“Publishing all tire selections for the full year will help drivers and teams with planning, but also allow for maximum flexibility in the event of a calendar change due to COVID-19 restrictions,” said Pirelli’s F1 boss Mario Isola.
“The choice of tires is similar to last year, but we have two races where the choice is softer. The first is Azerbaijan, where our C2 tire was not used for the last time , so we opted for the softest tires available - C3, C4, and C5.
” “Then we have Brazil where we will have C2, C3, and C4 tires this year, and the C1 tire in the last race  did not show a particular advantage over the medium [C2] tire. In both cases, softer tires could lead to the biggest strategic variation. ”
