Bridgestone reveals tire specs up to Silverstone

Formula 1 tire supplier Bridgestone has revealed the tire compounds which have been selected for up to Round 10 of the championship, the British Grand Prix. Under normal dry circumstances, two types of Slick must be used over the course of a race distance.

Since the start of 2007, each driver has been forced to make use of two types of dry weather tire compound in order to spice up the action in races. The softer of the two available (known as Option) is recognizable from the harder (Prime) courtesy of a green-painted sidewall.

"The Canadian and European Grands Prix take place on street courses where it is important to have good grip due to the slippery nature of the track surfaces," explains Hirohide Hamashima, Bridgestone's Head of Motorsport Tire Development.

"As these tracks are not used regularly for racing, even the allocations we bring will seem too hard when used on the Friday. By race day the circuit improvement and rubber laid will mean that the high grip of the Super Soft compound paired with the greater durability of the Medium compound should provide a good combination.

"The Silverstone circuit is historically the most severe on the calendar and now the new layout makes it even more severe. The new straight means a higher average speed and there is hard braking and fierce acceleration over a lap. As always, we will be very vigilant to watch tire temperature and wear. We expect we will see graining, even with the hard compound, but we believe that the Soft and the Hard compounds should allow exciting racing."

Bridgestone's four Slick compounds are the following:
Super Soft, Soft, Medium and Hard
