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."
