Storyline — Round of 12 begins on demanding Texas track: Coming off the recent race at Kansas Speedway, the NASCAR Cup Series returns to a mile-and-a-half track at Texas Motor Speedway this weekend.  Speeds will be high and teams must be cognizant of Goodyear‘s recommended air pressures, as well as their cars‘ geometry settings.  Getting too aggressive with a set-up can put undue stress on the tires, causing the sidewall to over-deflect and suffer damage to the point of air loss.

“We start the Round of 12 of the Cup playoffs this weekend at Texas, so there is a lot at stake for teams,” said Greg Stucker, Goodyear‘s director of racing.  “As we often see at the intermediate tracks, the speeds and loads make it important for teams to balance that ‘risk vs. reward‘ equation of speed vs. durability.  As always, we are working directly with the teams to help them understand how the air and car settings will affect the tires.  We provide a lot of data leading into the weekend so they can make informed decisions as to where the line is, and then those conversations continue throughout practice and the race to make sure everyone knows where they stand.”
