Bridgestone are taking their hardest compound Potenza tyres to Silverstone for the British Grand Prix.
Hirohide Hamashima - director of Bridgestone motorsport tyre development: "Silverstone is one of the more harsh circuits on the calendar, which is why we bring the hardest compound Potenza tyres from our range. It is a tough circuit for tyres in the sense of the layout and the track surface, which is one of the more abrasive we use.
"Graining is always a consideration when coming into the final complex, and tyre management of this is an important aspect to getting a good result. Drivers require good stability from their tyres to give them confidence through the high-speed turns. Good heat and wear resistance are also desirable here.
"The medium compound enabled a faster lap time over one lap, and if conditions are similar for the Grand Prix we would expect this to be the preferred tyre for qualifying. The hard compound enabled more consistent performance. However, if teams and drivers are able to manage the graining, the medium compound could be the preferred option in the race.
"As teams have now tested here so close to the Grand Prix weekend, we should see very close lap times as competitors have a good opportunity to find a good setup and maximise their cars to Silverstone's requirements."
