PirelliPirelli has announced its tire compound allocations for three more grands prix, meaning it has revealed its intentions for every race through Silverstone in July.

The soft and supersoft choices used for Monaco will be retained for the following Canadian Grand Prix, before supersofts and mediums are used on the streets of Valencia. The company feels that as Valencia is a faster layout than Monte Carlo, a different tire choice is appropriate despite both being street venues.

For the British GP, Pirelli is reverting to the hard and soft tires as used in this year's opening five rounds.

Pirelli's motorsport chief Paul Hembery said: "Selecting the tires is a very tough job for us, as in Montreal, Valencia and Silverstone we have no historical data, but we're feeling confident that the choices we have made, in close consultation with the teams and the FIA, should continue the Pirelli tradition of close racing that we have seen so far this year."
