Teams in both the NASCAR Sprint Cup and Nationwide Series run the same tire codes at Texas this weekend. These teams have run this left side tire code (D-4392) at Texas in both 2011 and 2012. This right side tire code is new to teams in these two series, though it has been run by teams in the NASCAR Camping World Truck Series at Texas for the past two seasons. Compared to what Sprint Cup and Nationwide teams have run at this track recently, this right side tire has a tougher compound for better wear. Goodyear held a test with the Gen-6 car at Texas on October 9-10, 2012. Teams and drivers participating in that test were No. 16 Roush Fenway Ford with Greg Biffle, No. 18 Joe Gibbs Racing Toyota with Kyle Busch, No. 27 Richard Childress Racing Chevrolet with Paul Menard and No. 42 Earnhardt Ganassi Racing Chevrolet with Juan Pablo Montoya. As on all NASCAR ovals greater than one mile 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.
