Grand Prix of Great Britain F1 2011: compounds selected by Pirelli

From the Grand Prize of Spain in Montmelo, Pirelli not brought the hard tyres, and after three races in general quite softer tyres, the Italian brand will lead to Great Britain, the same tire that we saw in the first five races of the season. We'll see how behave tyres as the Silverstone Circuit.
The choice for the English circuit, so it will be the hard and the soft tyre (Option) (Prime). The choice is logical, since Silverstone is a fast and soft tyres could spend too easily. But in spite of this, if it is cold, something that is never disposable in Great Britain, the problem could be another, and that the tyres harder cost them take temperature.
According to Pirelli, the pneumatic hard will serve to make the longer stints, for what you have chosen to bring soft rather than the medium tyre, so that teams have a tire that demonstrate its speed.

According to teams, the new compound that binds to the Pirelli family works pretty well, and will be used for the first time in career, along with the soft tyres, which will fulfil the role of Option.
Therefore, Pirelli brings Europe soft compounds (Option) and medium (Prime). Certainly harder compounds which were envisaged in principle help to deal with the heat of the Mediterranean coast, and it is these days in Spain we are having enough heat, so a little more of hardness in the tyres for sure it will be good.
Pirelli explains that the decision to change the compounds and bring the soft and medium instead of the superblando and soft is given not only by the climate, but also by the Valencian asphalt and the layout of the circuit, which considered that it might be very aggressive with the tyres.
