The following is from Bridgestone…
The fourth round of the 2013 MotoGP™ season takes place at the iconic Le Mans circuit after an exciting start to the championship that has yielded three different winners from the first three races.
At 4.185 kilometers in length, the Le Mans circuit places more emphasis on acceleration and braking rather than outright corner speed due to its many slow corners that are connected by a series of short straight sections. The relatively slow corner speeds means that Le Mans is the least severe circuit on the calendar for tires, and this combined with the generally cool temperatures means the front and rear slick compounds offered here are at the softest end of the spectrum. The soft rubber compounds ensure quick warm-up, high grip and excellent temperature retention.
At Le Mans, Bridgestone’s rear slick tires will be available in the extra-soft and soft compounds for CRT riders, and soft and medium compound for the riders on works bikes. The soft and medium rear slicks will be asymmetric in construction with harder rubber on the right shoulder, while the extra-soft rear slick will be symmetric. The front slicks for Le Mans will be the extra-soft and soft compound options. To ensure adequate tire warm-up in wet conditions, the main wet tire for Le Mans will be the soft compound.
Bridgestone slick compounds available: Front: Extra-soft, Soft Rear: Extra-soft (Symmetric), Soft, Medium (Asymmetric)
Bridgestone wet tire compounds available: Soft (Main), Hard (Alternative)
