Notes: This is the first time that Goodyear has brought this exact combination of left- and right-side tires to Las Vegas. This combination was run by Craftsman Truck Series teams at Charlotte earlier this season. This right-side code (D-4022) was run with a different left-side code by truck series teams at Las Vegas and Charlotte last year. As on all NASCAR ovals greater than one-mile in length, teams are required to run inner liners in all four tire positions at Las Vegas. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
