Pirelli has revealed the compounds to be used at Spa-Francorchamps and Suzuka.

Pirelli will take its medium, soft and supersoft compounds to Belgium in late August.

The P Zero White medium, P Zero Yellow soft and P Zero Red supersoft is the same combination previously used in Australia, Bahrain, China, last week's race in Baku, and to be used at the Hungaroring and Hockenheim.

A set of the medium and soft must be used at some point in the race and each driver must have both these sets available for the race, and must use at least one of them.

Each driver must also save for Q3 one set of the supersofts. 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 Spa weekend.

For the Japanese Grand Prix in October, the hard, medium and soft compounds have been nominated.

P Zero Orange hard, P Zero White medium and P Zero Yellow soft is the same combination that was used in Spain and will be seen again at Silverstone and Sepang.

Two sets of the hard must be used at some point in the race in Japan, when each driver will have both sets available and must use at least one of them.

Each driver must also save for Q3 one set of the softs. 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 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.
