*The tyre nomination for long-haul events has to be made 15 weeks in advance, whereas for European races the deadline is nine weeks in advance.
In accordance with the regulations, each driver must save for Q3 one set of the softest of the three nominated compounds. This set will be given back to Pirelli after Q3 for those who qualify in the top 10, but the remaining drivers will keep it for the race.
For the first five events of the season all 13 sets for each driver are identical and defined in the regulations: seven sets of the softest of the three nominated compounds, four sets of the middle compound and two of the hardest compound nominated.
About the Pirelli 2017 tyres:
- The range has been completely transformed, with new sizes (305/670-13 at the front and 405/670-13 at the rear) as well as new profiles, constructions and compounds.
- The compounds in particular make use of entirely new materials and a completely fresh design philosophy.
- Pirelli decided to additionally homologate a back-up compound alongside each of the five new base compounds. The extra compounds’ formula uses more traditional criteria compared to the new base compounds.
- Only the new-generation compounds will be available for the first part of the championship.
- The back-up compounds might be available later in the season. This will depend on any particular requirements once the identification of the 2017 cars’ real performance levels is complete.
