Notes: Both NASCAR series will run the same tire codes at Martinsville this weekend, though the Nextel Cup tires will be branded "Goodyear Eagle," while the Craftsman Truck tires will be branded "Goodyear Wrangler" . . . this is the first time Goodyear has brought this specific combination of left- and right-side tires to the track . . . Martinsville is the only track at which Nextel Cup teams will run this specific setup of left-and right-side tires . . . however, this right-side code (D-4110) will be run on all four tire positions at the series' two road course races -- Infineon Raceway and Watkins Glen International . . . Craftsman Truck teams are scheduled to run this same tire setup at Mansfield in May . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Martinsville.
