Notes: Teams in all three NASCAR series in action at Chicagoland this weekend will run the same tire codes, though the Sprint Cup and Nationwide tires will be branded “Goodyear Eagle,” while the Camping World Truck tires will be branded “Goodyear Wrangler”. This is the same combination of left and right side tires that teams in all three series have run at Chicagoland since 2011. This is also the same exact tire set-up that these teams have run at Homestead over that same span. NASCAR teams have also run this left side tire code (D-4392) with a different right side code at both Texas (all three series) and Darlington (Cup and Nationwide) 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.
