Notes: This particular combination of left- and right-side tires has been run at Indianapolis Motor Speedway since 2001 . . . Winston Cup teams have used this combination twice already this season at Pocono . . . in addition, Busch and Truck Series teams will run this combination at both Gateway and Pike's Peak in 2003 . . . as on all NASCAR ovals longer than one mile, teams are required to run inner liners in all four tire positions at Indianapolis . . . the air pressure in the inner liners must be 12-25 psi greater than that of the outer tire.

Goodyear Quote - Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Tire Development: "We are very confident with this tire set-up at Indianapolis for many reasons. We've run this combination at the Brickyard for the past two years, and teams are coming off a stretch where we've run these tires twice in the past month-and-a-half at Pocono. The Brickyard went through a diamond grinding process before last year's race, which resulted in a smoother surface and more grip than before. Having run this set-up on this surface in 2002 can only help teams feel more comfortable in 2003."
