Due to the track re-surfacing, Goodyear has brought a new tire combination to Michigan this week . . . teams in both the Sprint Cup and Nationwide Series did run this right-side tire code at Las Vegas earlier this season . . . this tire set-up came out of a Goodyear test at Michigan on April 3-4 . . . teams and drivers participating in that test were #2 Penske Racing Dodge with Brad Keselowski, #17 Roush Fenway Racing Ford with Matt Kenseth, #18 Joe Gibbs Racing Toyota with Kyle Busch, #24 Hendrick Motorsports Chevrolet with Jeff Gordon and #42 Earnhardt-Ganassi Racing Chevrolet with Juan Pablo Montoya. . . . compared to what was run at Michigan last year, there are both compound and construction changes on both the left- and right-side tires . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tire positions at Michigan . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire (Goodyear).
