Notes: This is the same combination of left- and right-side tires that NASCAR Nationwide Series teams have run at Chicagoland since 2011 . . . this is also the same tire set-up that these teams ran at Homestead from 2011-2013 . . . Nationwide teams have also run this left-side tire code (D-4392) with a different right-side code at both Texas and Darlington earlier this season . . . 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.
