Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same Goodyear tire codes at Charlotte this week . . . all tires will be branded with "Support Our Troops" as part of the Goodyear Gives Back program . . . while these teams have run this left-side tire code (D-4426) at Charlotte since 2012, last weekend at Charlotte was the first time NASCAR teams raced on this right-side code (D-4640) . . . this right-side is a Goodyear multi-zone tread tire, which incorporates two distinct compounds on the same tire -- one for endurance and heat resistance on the inboard two inches of the tread and one for traction on the outboard 10 inches . . . this inboard (Endurance Zone) features the same compound that was run on the same zone at Texas, while this outboard (Traction Zone) features the compound run at Charlotte last year . . . this tire set-up was first tested at Charlotte in December, and was confirmed in a March 10 tire test at the track with drivers Aric Almirola, Kasey Kahne, Martin Truex Jr. and J.J. Yeley . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte . . . 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” will be in the air over Charlotte Motor Speedway this Saturday and Sunday . . . this airship is based out of Pompano Beach, Fla., and will provide images for Fox Sports’ broadcasts of the NASCAR Xfinity and Sprint Cup races.
