Notes: Teams in both the NASCAR Sprint Cup and Xfinity Series will run the same tire set-up at Richmond this weekend . . . while these teams ran this left-side tire code (D-4632) at Richmond last September, this is the first time they have run this right-side code (D-4644) . . . this right-side is a Goodyear multi-zone tread tire, which incorporates two distinct compounds on the same tire . . . the inboard two inches of the tread (Endurance Zone) features the same compound that was run at Richmond last fall, while the outboard 10 inches of the tread (Traction  Zone) features a compound run at this track prior to that and will provide teams with more grip . . . this tire set-up came out of a Goodyear test at Richmond on April 7 . . . drivers participating in  that test were A.J. Allmendinger, Denny Hamlin, Brad Keselowski and Tony Stewart . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Richmond.
