Notes: This is the fifth race at which teams in the NASCAR Craftsman Truck Series teams have run this specific combination of left- and right-side tires in 2007. Prior to this weekend, Craftsman Truck teams have run this combination at California, Kansas, Dover and Michigan. As on all NASCAR ovals greater than one-mile in length, teams are required to run inner liners in all four tire positions at Kentucky. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
