Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same Goodyear tire codes at Charlotte this week . . . this is the same combination of left- and right-side tires these teams ran at Charlotte in May . . . NASCAR teams have run this left-side tire code (D-4428) at Charlotte since 2012, but this May was the first time they ran this right-side code (D-4640) . . . Xfinity teams also ran this right-side tire code at Darlington last month . . . 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 . . . 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.
