Notes: Teams in both the NASCAR Sprint Cup and Camping World Truck Series will run the same Goodyear tire codes at Martinsville this  weekend . . . this is the same left-side tire code (D-4588) that teams ran at this track in April . . . this is a different right-side tire code (D-4468) than the one run at Martinsville this spring, though it has been run at this track before . . . compared to what was run in April, this right-side features a slight compound change to help 'rubber in' the race track . . . Martinsville is the only track at  which NASCAR teams have run either of these two tire codes in 2014 . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Martinsville.
