Storyline - Goodyear brings traditional road course tire to Charlotte: The road course at Charlotte Motor Speedway has evolved over the past year, and the Goodyear tire recommendation has evolved right along with it. Since Goodyear held a test on the course last October, chicanes have been added on the backstretch and at the exit of the oval turn four, along with the elimination of some slow speed corners in the infield section. Because the two chicanes slow the cars down on the oval section, combined with the infield section, Goodyear decided on a traditional road course construction for its tire recommendation.
"Landing on the proper tire set-up for the Charlotte road course has proven to be a challenge," said Greg Stucker, Goodyear's director of racing. "The layout of the track has evolved significantly since we first tested in 2017, and that has led to our tire combination evolving as well. The unique combination of the road course and oval sections of the track requires a tire that can accelerate and decelerate well, along with carry the loads generated by the banking. In the end, we've decided upon our traditional road course construction, paired with a tread compound which optimizes grip across the different sections of the circuit. This was our control tire combination back in March, and though the organizational test in July was mostly run on a softer tread compound, back-to-back comparisons during that test demonstrated the March control was the better choice. Key also will be working with the teams to optimize inflation pressures, low enough to handle the tighter sections of the road course, but high enough to carry the loads of the oval."
Notes - New Goodyear tire code debuts at Charlotte: Like on all other NASCAR road courses on the three national series schedules, Cup and Xfinity teams will run the same Goodyear tire code on all four tire positions at Charlotte . . . Cup and Xfinity teams will run the same tire code . . . this is the first time this tire has been raced in NASCAR competition . . . Goodyear held tire tests at the road course in October 2017 and March 2018 (with a rain make-up day in April), as well as supporting the NASCAR organizational dates in July 2018 . . . as on other NASCAR road courses, teams will not run inner liners in their tires.
Wet Weather Tires - White-lettered tires on hand: Goodyear will bring its wet weather radials for use at Charlotte, should NASCAR decide that conditions warrant . . . Cup teams are allowed up to two sets of "wets" for practice and up to four sets for the race . . . Xfinity teams are allowed up to two sets of "wets" for practice and up to two sets for their race . . . this tire was run by NASCAR Xfinity Series teams at both Watkins Glen (practice and race) and Road America (practice) in August . . . the "Goodyear" and "Eagle" lettering on the sidewalls of the wet weather tires is white, not the standard, Goodyear yellow, to differentiate when the two are on track.
Upcoming tire test - Goodyear to hold session at Phoenix: Goodyear will hold a tire test at ISM Raceway next Tuesday and Wednesday, October 2-3 . . . teams scheduled to participate in the test are No. 6 Roush Fenway Racing, No. 11 Joe Gibbs Racing, No. 21 Wood Brothers Racing and No. 42 Chip Ganassi Racing.
