The FIA has confirmed that teams will be able to choose between three dry compounds during the race, rather than two, in an attempt to create differing strategies.
The current rules stipulate that Pirelli will provide two dry compounds, both of which must be used during the race.
However in 2016, the teams will be able to choose which two compounds they would like to use during the event for each driver, opening up the possibility of a rival selecting a different compound, and therefore different strategy.
“The tyre supplier will now provide three dry-weather compounds instead of two,” confirmed a WMSC statement.
“Of the 13 sets of dry tyres available to each driver, the tyre supplier will choose two for the race (only one of which must be used in the race), and one set (the softest available) that may only be used in Q3.
“Each driver may then choose their remaining 10 sets from the three available compounds.
“Unless intermediate or wet-weather tyres have been used, a driver must use at least two different specifications of dry-weather tyres – at least one of these must be the one chosen by the tyre supplier.”
HOW WILL IT WORK?
In consultation with the FIA, Pirelli will decide in advance which three compounds can be used at each race, and communicate this information to the teams.
The total number of sets that can be used during practice, qualifying and racing remains the same as it is currently: 13.
Pirelli will nominate two mandatory race sets for each car. Furthermore, one set of the softer compound will have to be kept for use in Q3 only.
The two mandatory sets chosen by Pirelli can be of two different compounds, from the three that have been nominated for the race weekend. These sets will obviously be identical for each team.
The remaining 10 sets can be chosen by each team, from the three compounds nominated for the race weekend.
The teams will make their choices within a deadline set by Pirelli. They will communicate their choices to the FIA, which will in turn tell Pirelli how many tyres to produce. The choices for each car will remain secret until 2 weeks before the race. If a team does not meet the deadline, the choice will be made by the FIA.
Once the choices for each car have been made, the FIA will continue to assign the tyres randomly via a barcode, as is the case currently.
The choices made by each team can vary for each of its cars: so each driverwithin a team can have a different allocation.
The tyres will be distinguished by different coloured markings on the sidewalls, as is currently the case.
DURING THE RACE
Teams will still have to give back tyres according to a certain schedule, but they can decide which tyres to give back at the following times:
– One set after the first 40 minutes of FP1
– One set at the end of FP1
– Two sets at the end of FP2
– Two sets at the end of FP3
The two mandatory sets nominated by Pirelli cannot be given back during practice and must be available for use in the race. At least one of these two sets must be used during the race – but the teams can decide which one.
The top 10 at the end of qualifying will still have to give back the set of the softer compound nominated for Q3, and start the race on the tyres with which they set their fastest time in Q2 (the same rule as is the case currently). All other drivers will be able to use the set that is saved for Q3 during the race.
