Pirelli has announced its tyre compound choices for three more grands prix, revealing the rubber it will bring to the Bahrain, Spanish and Monaco races.
Bahrain will feature the same medium/soft selection made for Australia and China, before the hard and soft compounds are used for Catalunya - in an effort to both handle the track's high lateral tyre loadings and promote strategic variety.
For Monte Carlo, Pirelli will bring its super soft for the first time in 2012, alongside the soft compound.
The firm's motorsport director Paul Hembery said: "Our nominations this year are designed to push the envelope of performance, as can be seen from our latest choices.
"Only the super soft tyre is the same compound as last year: the other compounds are softer and therefore faster, designed to encourage closer racing as well as a wider variety of strategies."
