Notes: This is the first time that Goodyear has brought this specific combination of left and right side tires to Texas, however, Craftsman Truck teams did run this left side code (D-4008) with a different right side at Texas last season. Truck teams did run this exact combination at Homestead in November 2006, and also ran the D-4008 left-side at California and Kansas last season.

As on all NASCAR ovals one mile or greater in length, teams are required to run inner liners in all four tire positions at Texas. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
