The 2011 Rolex Sports Car Series season was the twelfth season of Grand-Am's premier series. Continental Tire became the official tire partner for Grand-Am, replacing Pirelli after three seasons due to Pirelli's departure to FIA Formula One, GP2 Asia Series and GP2 Series (now FIA Formula 2 Championship) as well as increasing GP3 Series (now FIA Formula 3 Championship) involvement as an official tire partner after FIA World Motor Sport Council meeting verdict event in Geneva, Switzerland on June 24, 2010. The company purchased the naming rights of the RSCS's support series, the Grand-Am Cup Series, from KONI in 2010.
