When calculating which tyres we will bring to every circuit, we bear a number of factors in mind such as the weather conditions and the nature of the surface. We then make sure that we select two tyres that will complement each other in terms of racing spectacle and potential strategies as well. So we’ve come up with tyre nominations that should not only be well suited to the characteristics of each circuit but also provide a great race for the drivers and spectators, with plenty of scope for the teams to exercise their strategic skills. Selecting the tyres 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.
