Notes: Both the NASCAR Winston Cup Series and Busch Series will compete on the same tires this weekend at Kansas . . . this will be the first time these teams will run this particular combination of left- and right-side tires at Kansas . . . this is the third straight year Goodyear has brought this left-side code (D-6352) to Kansas, though this will be the first appearance for this right-side code (D-6372) here . . . in 2003, major NASCAR teams have run this same combination at Charlotte, Dover and Kentucky (Busch and Truck Series only) .
. . in addition, teams have run this left-side code with a different right-side code at California (D-6354), Chicago (D-6356), Michigan (D-6354) and Texas (D-6364) . . . teams are required to run inner liners in all four tire positions at Kansas . . . the 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: "As a new race track ages, the asphalt changes and loses some of its initial grip. Since the inaugural event at Kansas in 2001, we've continued to adjust the right-side recommendation to account for this change. This year we've brought our Charlotte-Dover tire set-up to Kansas, so this will be the fourth race Winston Cup teams have run on this combination in 2003."
