Tuesday 20 July 2010 Bridgestone slick compounds available: Front: Medium, Hard. Rear: Medium, Hard (asymmetric) Round nine of the season takes the MotoGP paddock to North America for the first time in 2010, to the peninsula of Monterey on the west cost of California. Mazda Raceway Laguna Seca is one of the most famous and iconic circuits on the calendar, and this season Bridgestone have adopted a different approach. This year Bridgestone have selected asymmetric rear slick tyres for the United States Grand Prix, having listened to calls from riders following last year's race. The asymmetric rear slicks comprise a harder compound in the left shoulder, for improved durability and stability at high temperature, and a softer compound in the right shoulder, for improved warm-up performance. This softer right shoulder will be particularly beneficial through turns three, four and ten, the circuit's main right-handed corners. Laguna Seca is the shortest circuit on the calendar with a short main straight of just 0.9km, meaning the tyres spend less time upright and therefore have less time to cool down, resulting in higher tyre temperatures than the ambient and track conditions would suggest. The circuit's elevation changes, particularly through the Corkscrew complex, require a good machine setup, and place a lot of importance on the performance of the front tyre.
