Notes: While teams in both the NASCAR Sprint Cup and Camping World Truck Series will run the same left-side tire code (D-4604) at Kansas this week, they will run distinct right-side codes. In the Sprint Cup Series, this is the same left-side code that teams ran at Kansas last October. This is the first time they have run this right-side code (D-4586). This right-side is a single compound tread and features a slight change from what was run on the traction zone of last October's multi-zone right-side at Kansas. This tire set-up came out of a Goodyear tire test at Kansas on April 14, where one team per Sprint Cup organization was invited to that test. 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 those inner liners should be 12-25 psi greater than that of the outer tire.
