Notes: Teams in all three NASCAR series will run the same tire codes this weekend, though the Nextel Cup and Busch Series tires will be branded "Goodyear Eagle," while the Craftsman Truck tires will be branded "Goodyear Wrangler". Teams in all three of these series ran this specific combination of left- and right-side tires at a triple-header weekend at California Speedway earlier this season. Truck series teams also ran this combination at Kansas in late-April.

This left-side code (D-4078) is new to the Goodyear tire lineup for 2007.This right-side code (D-4062) was run at Dover, Kansas and Michigan in 2006.

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