Storyline – Dover puts pressure on right-front pressure decision: Since Dover International Speedway is just one mile in length, it fits into the list of tracks at which NASCAR Cup teams run the higher horsepower (750 hp), higher downforce package. That, combined with the steep banking and high speeds we see at the "Monster Mile," the amount of load on the right-front tire must be a focus. Goodyear will be working with Cup teams leading into the event and throughout the two days at the track to emphasize the importance of the minimum recommended air pressure. Going below the minimum may get a car more grip, but that is clearly a risk vs. reward proposition. Low air pressure under the conditions teams will face at Dover can damage the tire and result in air loss. With no practice leading into Saturday’s race, teams must be especially mindful with their initial set-ups, and then not crank up the aggression as they move to Sunday.

"While we all have some experience with running this rules package on fast, high-banked tracks, having run Dover and Bristol in 2019 and Bristol again this season, it is always important to keep on top of the delicate balance between performance and durability," said Greg Stucker, Goodyear’s director of racing. "Dover, with this current package, is a big challenge for all of us, so we will be working with the teams to re-emphasize the data. Gaining as much grip as possible is always front and center for these teams, and one tuning tool they use to accomplish that is air pressure. But as they say, ‘to finish first, you must first finish.’ Observing our recommendations at Dover, especially on the right-front, is key to that. This left-side has a little more grip than what we brought to Dover last year, so hopefully that will take some pressure off teams looking to the right-front to do all the work."

Notes – New tire set-up at Dover for all three national series: Teams in NASCAR Cup, Xfinity and Gander RV & Outdoors Truck Series will run the same tire set-up at Dover this weekend . . . this is a new combination of left- and right-side tires for Dover . . . these teams have run left-side tire code at Auto Club, Darlington and Homestead this season . . . this is a brand new right-side tire code . . . compared to what was run at Dover last fall, this tire set-up features a construction update on both sides of the car and a compound change on the left-side for more grip . . . Dover is unique among NASCAR ovals one mile or less in length, in that inner liners are required on all four tire positions . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
