Chicago Goodyear Tire Notes

This is the first time Goodyear has brought this tire setup to Chicagoland, though teams in these two NASCAR series have raced on it already in 2008 . . . this exact combination of left- and right-side tire codes has been run by Sprint Cup and Nationwide Series teams earlier this season at Texas . . . in addition, this left-side tire code (D-4134) was also run with a different right-side code at Dover (both series), Michigan (Sprint Cup only) and Kentucky (Nationwide only) . . . these teams are also scheduled to run this specific tire combination at Homestead in November . . . compared to what was run at Chicagoland last season, this tire setup features a revised construction on both sides and a tougher right-side compound for better wear . . . as on all NASCAR's 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. The estimated pit window is every 50-55 laps, based on fuel mileage. Goodyear PR
