Pirelli will give its medium compound tyre its race debut in the latest round of the F1 season this weekend in Valencia.
The tyres were tested in Canada a fortnight ago during Friday practice and will now be used as the prime tyre for the European Grand Prix.
Pirelli's soft compound rubber will be the option tyre for the weekend having served as the prime selection for the last two events in Monaco and Montreal.
“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,” Pirelli motorsport director Paul Hembery said. “Tyre 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 tyres, 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 tyres 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 tyre in Spain, and this was the compound that the teams tested during Friday's free practice in Canada, giving us plenty of useful data.”
