Notes: Teams in both the NASCAR Sprint Cup and Camping World Truck Series will run the same combination of left- and right-side tires at Kansas this weekend . . . while these teams ran this left-side tire code (D-4604) at this track last season, this is the first time they have run this right-side code (D-4630) at Kansas . . . for Sprint Cup teams, compared to what they ran in at Kansas in 2014, this right-side tire features a construction change that brings it into line with what is run at other speedways . . . Cup teams have run this right-side at both Las Vegas and Talladega already this season . . . for Camping World Truck teams, who ran their own right-side at Kansas last May, this tire features both a construction and slight compound change . . .  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.
