Notes: Teams in both the NASCAR Sprint Cup and Nationwide Series will run the same Goodyear tire codes at Richmond this week. This is the first time NASCAR teams have run on either of these two codes. This right-side code (D-4610) is one of Goodyear's multi-zone tread tires, which combines two distinct tread compounds on the same tire. The outboard 10 inches of tread surface (traction zone) is the same compound run on the entire right-side tire at Richmond last season. The inboard two inches of tread surface (endurance zone) features a slightly tougher, more heat resistant compound. Compared to what was run at Richmond last year, this new left-side code (D-4608) features a compound change to give the cars more grip. This tire set-up came out of a Goodyear tire test at Richmond last October 22-23. As on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Richmond.
