Pirelli will bring the following three compounds to the fourth round of the 2016 Formula One season in Russia (April 28-May 1)
P Zero White medium
P Zero Yellow soft
P Zero Red supersoft
These are the tyres that Pirelli has said must be used at some point in the race:
One set of P Zero White medium
One set of P Zero Yellow soft.
Each driver must have both these sets available for the race, and must use at least one of them.
There are the tyres assigned for Q3 in qualifying:
One set of P Zero Red supersoft
Following on from the 2016 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 – as is the case currently.
The teams are free to choose the remaining sets; making up 13 sets in total for the weekend.
Confirmation that Pirelli will not be taking the Ultra Soft compound to the Russian Grand Prix means the compound is unlikely to make its debut until the Monaco Grand Prix at the end of May.
