Storyline – New Texas tire set-up comes out of recent test at track:This is the fourth NASCAR Cup weekend since the repave at Texas Motor Speedway, and it is truly a team effort in ensuring the best racing possible. Goodyear held two tire tests at the facility this year alone, the speedway has been preparing the track surface for the better part of two weeks by dragging tires to lay down rubber, and NASCAR has been involved every step of the way. Directly after a repave, track surfaces have not had much of a chance for the asphalt to degrade, and the relative smoothness of the surface makes it difficult to wear tires organically. So, in addition to track prep efforts, Goodyear has brought a different tire set-up for the Cup and Xfinity cars to Texas this weekend, including the right-side tire it has run at Michigan International Speedway that will introduce more wear, run cooler and promote better racing.

“Texas has been a big priority for Goodyear this year after having held tests there in both January and August,” said Greg Stucker, Goodyear director of racing. “When tracks go through a repave and reconfiguration, like Texas did for 2017, it’s important to keep up with the track surface and how it changes over those first several years. When we tested in August, with the goal of introducing more tire wear on the smooth surface, we decided upon the Michigan right-side tire for the Cup and Xfinity cars. Michigan also had a repave in the recent past and this tire has done a nice job of generating tire wear there, and will be a good fit for Texas.”

Notes – Cup Xfinity cars on new tire set-up at Texas: Teams in both the NASCAR Cup and Xfinity Series will run the same tire set-up at Texas this weekend . . . this is a different combination of left- and right-side tires than these teams ran at Texas earlier this season . . . this is the first time teams in either Cup or Xfinity have run this left-side tire code, though they have run this right-side code at Michigan in 2018 . . . compared to what was run by these teams at Texas in April, this left-side tire features a construction update to bring it into line with what is run at other speedways, while this right-side tire features a compound change to introduce more wear and be more heat resistant . . . this tire combination came out of a Goodyear test at Texas on August 14-15 . . . drivers participating in that test were Alex Bowman, Kurt Busch, Austin Dillon, Joey Logano and Martin Truex Jr. . . . as on all NASCAR ovals greater than one mile in length, teams are required to run 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.
