With the complete re-pave of Darlington Rcaeway since last season, Goodyear has tested extensively at the track and brought a new combination of left- and right-side tires for teams to race on this weekend . . . Goodyear ran it’s first two-day test at Darlington with drivers #16-Greg Biffle, #24-Jeff Gordon and #12-Ryan Newman in mid-March, and settled on it’s right-side tire recommendation during that session . . . the tire manufacturer scheduled a one-day continuation test with the same drivers for early-April, and confirmed it’s left-side recommendation at that session . . . Darlington is the only track at which NASCAR teams are scheduled to run this specific combination of left- and right-side tire codes this season . . . however, teams will run this right-side code (D-4130) with a different left-side code at Charlotte later this month . . . teams in both the NASCAR Sprint Cup and Nationwide Series will run the same tire codes this weekend . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Darlington . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire. The estimated pit window is every 54-58 laps, based on fuel mileage.(Goodyear PR), see full report, codes, pressures and more on my Darlington Race Info page.(5-9-2008)
