Notes: This Goodyear Eagle tire combination is the same one run at Daytona since July 1999, making this the ninth consecutive race for these left- and right-side codes at "The World Center of Speed" . . . Daytona is the only track this tire combination will be run on this season, though it is similar to the one run at NASCAR's other restrictor plate track -- Talladega . . . both the Winston Cup and Busch Series will run the same tire codes this week . . . at Daytona, as on all NASCAR ovals larger than one mile, teams are required to run inner liners in all four tire positions . . . 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: "Goodyear has a great history with this tire set-up at Daytona. This is the ninth straight race we've brought this left-right combination to this superspeedway, so teams benefit by having a solid book of notes to work from on these tires. For the most part, tires are generally only a story on restrictor plate tracks in the area of pit strategy. Especially since NASCAR has mandated that teams run smaller fuel cells at Daytona, teams can feel comfortable mixing in two-tire stops at certain points of the race, without really sacrificing anything in performance."
