Notes: Teams in all three NASCAR series will run the same Goodyear tire  codes at Daytona throughout Speedweeks . . . this is the same  combination of left- and right-side tires that these teams have run at  Daytona since July 2013 . . . Xfinity and Camping World Truck teams  have also run this tire set-up at Talladega over that same span . . .  Sprint Cup teams ran this set-up at Talladega for two races -- October  2013 and May 2014 -- before changing the right-side tire at that track  last October . . . as on all NASCAR ovals greater than one mile in  length, teams are required to run inner liners in all four tire  positions at Daytona . . . air pressure in those inner liners should be  12-25 psi greater than that of the outer tire.
Goodyear Blimp: Goodyear's "Spirit of Innovation" airship, based out of  Pompano Beach. Fla., will be in the air over Daytona International  Speedway throughout Speedweeks . . . the ship will be a part of  television coverage for the Sprint Unlimited and Sprint Cup qualifying  during the first week, and the Budweiser Duels and the Camping World  Truck, Xfinity and Sprint Cup races during the second week.
