Paul Hembery: "We've seen some fantastic street races so far this season, with the last grand prix in Canada being one of the highlights of the year, so we hope that Valencia will continue this pattern although it's notoriously difficult to overtake there. Tire wear on this circuit is likely to be quite high because of the track layout, the nature of the surface, and also the weather conditions, which should be very warm.
"For all these reasons, we've selected the medium and soft tires, which should provide the teams with a good level of resistance, plenty of different opportunities for strategy and about a second per lap difference between the compounds. The PZero White tires have been adjusted slightly from our original specification to make them a bit more durable, along the lines of the tweak we made to the PZero Silver hard tire in Spain, and this was the compound that the teams tested during Friday's free practice in Canada, giving us plenty of useful data."
