Teams in both the NASCAR Sprint Cup and Nationwide Series will run the same combination of left- and right-side tires at Texas this weekend . . . this is the first time teams have run either of these two tire codes . . . compared to the tire set-up NASCAR teams ran at Texas in 2009, this left-side tire features a new construction, mold shape and compound to offer more grip, while this right-side tire features a new construction that brings it in line with what has been run at Las Vegas and Charlotte and a new compound to improve wear . . . this tire combination came out of a Goodyear tire test at Texas this past January 19-20 . . . teams and drivers participating in that test were the No. 2 Penske Racing Dodge with Kurt Busch, No. 14 Stewart Haas Racing Chevrolet with Tony Stewart, No. 16 Roush-Fenway Ford with Greg Biffle and No. 83 Red Bull Racing Toyota with Brian Vickers . . . 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. The estimated pit window is every 50-55 laps, based on fuel mileage. (Goodyear), see tire pressures, codes and more on my Texas Race Info page – Goodyear section.(4-16-2010)
