Notes: This is the second time that Goodyear has brought this specific combination of left- and right-side tires to Charlotte . . . both the Nextel Cup and Busch Series will run the same tire codes this weekend . . . while this left-side tire code (D-6852) has been run at many major NASCAR tracks this season -- California, Chicago, Kansas, Michigan and Kentucky (no Cup) -- this right-side code (D-6876) is unique to Charlotte . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte . . . inflation on those inner liners should be 12-25 psi greater than that of the outer tire.
Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Racing: "We originally developed the Fontana/Chicago/Kansas/Kentucky tire set-up at Charlotte last October. When the track surface was ground this spring, we had to re-test and redesign the set-up. The new 'grooved' surface proved to be more abrasive, with much more grip, during the May race events."
