Formula 1 tire supplier Pirelli has confirmed the three compounds that will be available to teams for the Russian Grand Prix on May 1.
Following a change in the regualations concerning tires for the 2016 season, teams will now have a choice of three compounds across the course of a weekend, rising from two in 2015.
Teams are required to use the softest compound tire in Q3, and must use two pre-defined compounds during the race.
For the Russian Grand Prix at the Sochi Autodrom, teams will have a pick of the super-soft, soft and medium tires, reflecting the low-grip nature of the technical circuit.
All drivers entering Q3 will be required to complete the session on super-soft tires, while the soft and medium compounds must be used during the race.
Pirelli has so far confirmed its compounds for the first four grands prix in 2016, using the super-soft/soft/medium selection for Australia, Bahrain, China and Russia.
This year’s Russian Grand Prix has moved to a much earlier slot, having taken place in October for its first two runnings as a world championship event.
