The 2011 Rolex Sports Car Series season was the twelfth season of Grand-Am's premier series. Continental Tire became the official tire partner and supplier for Grand-Am, replacing Pirelli after three seasons due to Pirelli's departure to FIA Formula 1 World Championship, 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 and supplier after FIA World Motor Sport Council meeting verdict event in Geneva, Switzerland on June 24, 2010.[1][2] The company purchased the naming rights of the RSCS's support series, the Grand-Am Cup Series, from KONI in 2010.
The season began with the Rolex 24 at Daytona on January 29[3] and finished with the EMCO Gears Classic at the Mid-Ohio Sports Car Course on September 17.
A notable change is the television coverage. In contrast to 2010, about half of the races were not televised live.
