Notes: Teams in the NASCAR Sprint Cup Series will run the same combination of left and right-side tires they ran twice at Kansas last season. More recently, these teams ran this right-side tire code (D-4408) at Fontana earlier this season. While Sprint Cup and Camping World Truck teams will run the same right-side code at Kansas this weekend, they will run distinct left-side codes. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Kansas. Air pressure in the inner liners should be 12-25 psi greater than that of the outer tire.
