Storyline – Roval demands both road course and oval elements to tires: Just like the name “roval” is a mash-up, Goodyear’s tire recommendation for the course follows suit, with both road course and oval elements. In the road course column, Goodyear brings a road course construction. In the oval column, this course has a majority of left-hand turns including running on the majority of Charlotte Motor Speedway’s 1.5-mile oval. As such, Goodyear’s air pressure recommendations reflect that, with the right-front position having the highest psi number.
“Even though the Charlotte roval uses a good portion of the track’s oval and is a primarily left-hand course, we bring a road course construction there, similar to what we bring to a traditional road course, like a Watkins Glen,” said Greg Stucker, Goodyear’s director of racing. “Like on other road courses, the front tires will have higher pressure recommendations than the rears to help handle the hard braking in and hard acceleration off the corners. The right-front tire position will have the highest pressure recommendation because the cars will lean on that corner the car most because of the majority of left-hand turns.”
Notes – No changes to tires run at Charlotte roval: NASCAR Cup and Xfinity teams will run the same Goodyear tire code on all four tire positions on the Charlotte roval . . . this is the same tire these teams ran on this course in both 2019 and 2020 . . . this tire code was also run by Cup and Xfinity teams at the Indianapolis road course in August . . . as on other NASCAR road courses, teams will not run inner liners in their tires on the Charlotte roval.
Wet Weather Tires – White-lettered tires on hand: Goodyear will bring its wet weather radials for use by teams in all NASCAR series at Charlotte, should NASCAR decide that conditions warrant . . . Cup teams will have up to 5 sets of wets, while Xfinity teams will have up to 4 sets of wets . . . this tire was last run in NASCAR competition by teams in all three of NASCAR’s national series at COTA in May . . . Goodyear’s wet weather tires were also run by teams in both of these series at Charlotte last season . . . in addition to the obvious difference of a tread pattern versus Goodyear’s dry weather “slick” tires, the “Goodyear” and “Eagle” lettering on the sidewalls of the wet weather tires is white, not the standard yellow.
