Notes: Teams in all three NASCAR series in action at Texas this week will run the same tire set-up . . . this is the same combination of left- and right-side tires that these teams have run at Texas since the beginning of 2014 . . . Sprint Cup, Xfinity and Camping World Truck teams have also run this tire combination at Chicagoland earlier this season, and will do so again at Homestead in two weeks . . . this right-side tire code (D-4618) employs Goodyear's multi-zone tread technology, which combines two distinct tread compounds on the same tire -- the outside 10 inches of the tread features a compound that is designed for grip, while the inside two inches of the tread is toughened to enhance durability on the part of the tire sees the most heat and takes the most abuse . . . 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.
