Notes: This is the same combination of left- and right-side tires that NASCAR Nationwide Series teams have run at ChicagoLand over the last two seasons. This is also the same tire set-up that these teams ran at Texas and Homestead in 2011 and 2012. This season, Nationwide teams ran this left-side tire code (D-4392) at both Texas and Darlington, though with different right-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 ChicagoLand. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
