Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same tire set-up at Talladega this weekend . . . this is the same combination of left- and right-side tires that Sprint Cup teams ran at this track last October . . . for Xfinity teams, they ran this left-side tire code (D-4596) their last race at Talladega last May, but with a different right-side code . . . compared with what Xfinity teams ran a year ago, this right-side code (D-4630) features a compound change for better wear . . . earlier this season, teams in both of these series ran this left-side code at Daytona in February and this  right-side code at Las Vegas in March . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Talladega . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
