The following is from Bridgestone…
Mugello is the venue for round five of the 2013 MotoGP™ season and the first of two races on the Italian peninsula this year. The circuit is both a rider and fan favorite owing to its sinuous layout and picturesque setting.
The Mugello circuit is fast and flowing with one of the longest straights on the MotoGP calendar. This straight is preceded by the horseshoe-shaped Bucine corner which slingshots the riders down the hill towards turn one at speeds approaching 350km/h. Consequently, the braking zone into San Donato is the most vicious in MotoGP and requires front tires with very high levels of structural stability.
In addition to the stability needed under heavy acceleration and braking, the sweeping sections of Casanova-Savelli and Biondetti, as well as high-speed corners such as Arrabbiata 1 and 2, require very high levels of grip from the edge of the tire. With nine right-handed corners compared to just six left-handers, Bridgestone will provide asymmetric rear slicks with slightly harder rubber on the right shoulders compared to the left.
One of the key performance requirements of the rear slicks developed for Mugello is an ability to withstand very high temperatures for sustained periods. At this circuit, the riders tend to accelerate hard at high lean angles which generates extreme heat, so all the rear slicks Bridgestone will supply this weekend will be in the heat-resistant ‘Special Construction’ specification. This specification of rear slick ensures superior rider safety and consistent grip levels in extreme operating conditions.
Rear slick options for the CRT riders are the soft and medium compound, while the works riders will be offered the medium and hard compound rear slicks. Bridgestone’s front slick tire compounds for the Italian Grand Prix are devised to ensure maximum braking and cornering stability, while catering to the potential for cool conditions.
Wet conditions are forecast for this weekend and Bridgestone’s main wet tire for Mugello will be the hard wet tire, with each rider able to select up to two front and rear tires in the alternative, soft specification if they desire.
Bridgestone slick compounds available: Front: Soft & Medium. Rear: Soft, Medium & Hard (Asymmetric)
Bridgestone wet tire compounds available: Hard (Main), Soft (Alternative)
