Notes: Teams in both the NASCAR Sprint Cup and Nationwide Series will run the same tire set-up at Daytona this week. This is the first time these teams will be running either of these two tire codes. This tire combination came out of a Goodyear tire test at Daytona on April 16-17. Teams and drivers participating in that test were the No. 1 Earnhardt Ganassi Racing Chevrolet with Jamie McMurray, No. 5 Hendrick Motorsports Chevrolet with Kasey Kahne, No. 10 Stewart Haas Racing Chevrolet with Danica Patrick, No. 16 Roush Fenway Racing Ford with Greg Biffle, No. 17 Roush Fenway Racing Ford with Ricky Stenhouse Jr., No. 18 Joe Gibbs Racing Toyota with Michael McDowell, No. 21 Wood Brothers Racing Ford with Trevor Bayne, No. 33 Circle Sport Chevrolet with Austin Dillon and No. 99 Roush Fenway Racing Ford with Carl Edwards. Compared to what was run at Daytona in February, this tire set-up features a compound change on both sides of the car and a construction change to the left side to bring it into line with what has been run at other tracks. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Daytona. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
