Formula 1 tyre supplier Pirelli has confirmed the compound choices for the opening four rounds of the 2015 season.

The yellow-banded Soft tyres and white-banded Mediums will be used in Australia, China and Bahrain.

The Medium, along with the orange-banded Hard tyres, will be available in Malaysia.

The selection is the same as the corresponding events from 2014, despite the minor modifications which Pirelli has made to its P-Zero tyres.
