  • Bridgestone slick compounds available: Front: Soft & Medium. Rear: Extra-soft (Symmetric), Soft & Medium (Asymmetric)
  • Bridgestone wet tyre compounds available: Soft (Main), Hard (Alternative)

 

Home to the famous Corkscrew, Laguna Seca features rapid changes in elevation and direction so the tyres supplied must provide high levels of edge grip and front-end stability. The circuit’s seaside location often brings morning cloud cover that dissipates in the afternoon and so the tyre compound choice for this race must perform over a wide range of conditions. The changeable weather can also make finding an ideal setup for the 3.610 kilometre circuit challenging for the teams. There are seven left-hand turns compared to just four right-hand turns, so the asymmetric rear slicks feature slightly harder rubber on the left shoulder though overall, the rubber compounds used in the rear tyres at Laguna Seca are towards the softer end of Bridgestone’s range.

Laguna Seca is one of only four events on the calendar where Bridgestone brings the extra-soft compound rear slick for the CRT riders, who will also be allocated the soft compound rear slick. Rear slick compounds for the MotoGP riders will be the soft and medium compounds. Front slick tyre options for Laguna Seca are the soft and medium compound, while the main wet tyre for the United States Grand Prix will be the soft compound wet tyre.

Hiroshi Yamada – Manager, Bridgestone Motorsport Department

“Laguna Seca has only been back on the MotoGP calendar since 2005 but it already is one of the most anticipated races of the season as its spectacular, counter-clockwise layout often produces close racing. This circuit features big changes in elevation and some tight corners and although it has a low average speed for a MotoGP circuit, sections like the Corkscrew are some of the most challenging on the calendar. As we approach the halfway point of the season the championship standings are very close with thirty-seven points separating the top five riders, so there is a lot at stake this weekend. I am looking forward to what should be an exciting weekend at Laguna Seca.”

Shinji Aoki – Manager, Bridgestone Motorsport Tyre Development Department

“Laguna Seca is a circuit with a relatively low average speed and although it isn’t overly demanding on tyres, it does present Bridgestone with some challenges. The circuit is located in the hills close to the sea which causes large variations in track temperature between the morning and afternoon sessions, so our tyre allocation has to work over a substantial range of conditions. Particular parts of the circuit also test the tyres, the most famous of these being the Corkscrew which features a fast change of direction and elevation that requires a lot of feel from the front tyre. Also, the right-handed turns three and four right are important to get right for a good lap time so our rear slicks need to have good temperature retention on the right shoulders for these slow, ninety degree corners. Like the last round at Sachsenring, this circuit is run in a counter-clockwise direction and has more left-handed than right-handed corners so we provide asymmetric rear slicks with harder rubber on the left shoulder.”
