This Goodyear Eagle tire combination is the same one run at Chicagoland since the NASCAR Winston Cup and Busch Series began running there in July 2001 . . . Chicagoland is the only track this tire combination will be run on this season, though this particular left-side code (D-6352) will be run with different right-side codes at Texas, California, Charlotte, Michigan and Kansas . . . both the Winston Cup and Busch Series will run the same tire codes this week . . . as on all NASCAR ovals longer than one mile, teams are required to run inner liners in all four tire positions at Chicagoland . . . air pressure in the inner liners must be 12-25 psi greater than that of the outer tire.
Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Tire Development:
"This is the third straight year we have brought this tire set-up to Chicagoland, so teams should have a lot of notes to work from. The biggest change we expect to see is that as the track ages, the asphalt will lose grip and lead to a broader racing groove through the corners. Drivers will experiment with different racing lines, depending on what the car is asking for, and that will lead to more side-by-side racing."
