Pirelli has chosen the same three compounds that it had announced for the season-opening race in Australia: the supersoft, the soft and the medium.

The soft and the medium will be the mandatory compounds that will need to be used at some point during the race.

The Italian manufacturer has again assigned the supersoft tyres for Q3.

All drivers must save one of the softest compounds for Q3, and the set will then be returned to Pirelli only by those who qualified in the top 10.

The rest of the drivers will have the extra set available to them for the race.

Teams must choose their Bahrain GP tyres by December 24.
