Having already revealed the choices for the season-opening Australian and Chinese Grands Prix, the Italian manufacturer has announced its selections for the Bahrain and Russian Grands Prix.

For the Bahrain event, Pirelli has chosen the supersoft, the soft and the medium, the same selection it will take to China.

Either the soft or the medium must be used at least once during the race, while the supersoft is the tyre chosen for Q3.

The ultrasoft, the supersoft and the soft will be taken to Russia.

The softest compound will be used in Q3, while one the other two must be used at some point in the race.

All drivers will use the same compounds in the first five races of the 2017 season, leaving the choices down to Pirelli.

Back-up compounds will also be available alongside each of the five new base compounds, the former "using a more traditional criteria compared to the new base compounds".
