NASCAR Sprint Cup Series , Race No. 7 – Duck Commander 500
Texas Motor Speedway (1.5-mile oval) – Fort Worth, Tex.

While teams in both the NASCAR Sprint Cup and Xfinity Series will run the same left-side tire code at Texas this week, they will run their own right-side codes. In Sprint Cup, like last year at Texas, this right-side tire code employs Goodyear's multi-zone tread technology, which combines two distinct tread compounds on the same tire , the outboard 10 inches of the tread (Traction Zone) features a compound that is designed for grip, while the inboard two inches of the tread (Endurance Zone) is toughened to enhance durability on the part of the tire sees the most heat and takes the most abuse.

Compared to what was run at Texas last season, this right-side tire (D-4686) features a construction change, and a compound change on the outboard 10 inches to give the cars more grip while the left-side tire (D-4684) features an updated construction and mold shape, as well as a compound change for more grip.

This tire set-up came out of a test at Homestead last December 14; traditionally, Texas, Homestead and Chicagoland have all lined up with the same tire set-up. The drivers participating in that Homestead test were Kevin Harvick, Chase Elliott, Brian Scott and Martin Truex Jr..

Teams as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Texas, air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
