2010 Rolex Sports Car Series

The 2010 Rolex Sports Car Series season was the 11th season of the Grand-Am Rolex Sports Car Series presented by Crown Royal Cask No. 16. It began on January 30 with the Rolex 24 at Daytona and concluded on September 12 at Miller Motorsports Park.

This was Pirelli's final season as the sole tire partner and supplier in Rolex Sports Car Series as the company announced that it would not renew its contract at the end of the season and thus coinciding with its entry into FIA Formula 1 World Championship, GP2 Series and GP2 Asia Series in 2011, and its discontinuation of its Grand-Am program. Continental would take over as official Rolex Sports Car Series tire partner beginning from 2011 season.

Schedule
Late in the 2009 season, the series tested at Indianapolis Motor Speedway as a proposed addition to the schedule, however this failed to materialize for 2010.

The final schedule featured many changes and realignments from 2009. Laguna Seca has been removed, leaving Miller as the only race in the Western United States. The race at Lime Rock on Memorial Day returned after being absent in 2009, this time with the DP class in addition to the GT class. Meanwhile, the race at Barber Motorsports Park was held jointly with the IndyCar Series' Indy Grand Prix of Alabama.
