Notes: This is the same tire set-up that Goodyear brought to California in February . . . this exact combination of left- and right-side tires has also been run by both Nextel Cup and Busch Series teams at Dover and Michigan in 2007 . . . in addition, Busch teams ran this combination at Kentucky in June . . . teams have also run this left-side code (D-4078) with a slightly different right side at Texas and Chicagoland earlier this season . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at California . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
