Pirelli will bring the following three compounds to the fifteenth round of the 2016 Formula One season in Singapore*, to be held (September 15-18) on its street circuit:
P Zero Yellow soft
P Zero Red supersoft
P Zero Purple ultrasoft

These are the tyres that Pirelli has said must be used at some point in the race:
One set of P Zero Yellow soft
One set of P Zero Red supersoft.

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 Purple ultrasoft

Following 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.

The teams are free to choose the remaining 10 sets; making up 13 sets in total for the weekend.

*The new 2016 tyre regulations mean that tyre nomination for long-haul events have to be made 14 weeks in advance, whereas for European races the deadline is eight weeks in advance.
