Scenario – Atlanta now in superspeedway group for Cup cars: Atlanta Motor Speedway is the first track NASCAR Cup teams will return to after a previous race in 2022. And while this is the second time, it’s worth remembering that Atlanta’s mile and a half has been repaved and reconfigured on the last off-season and is now in the superspeedway track category with Daytona International Speedway and Talladega Superspeedway as far as the racing package goes. That means Cup teams will race under the superspeedway package of 510 horsepower and a seven-inch-high fin, as opposed to 670 horsepower and a four-inch blade at other intermediate tracks.
Another factor that will come into play – as with any repaving – is that the new asphalt will have a high level of grip on a relatively ‘smooth’ track surface, which will lead to an increased level of heat in the tyres. Managing these temperature levels will be important, and Goodyear designed the Atlanta tire setup in anticipation of low tire wear on the new surface by having less gauge (thickness) in the tread to dissipate some of this heat.
“The only advantage we have in the Cup Series in Atlanta this week is that these teams already have one race under their belt at this track with this package,” said Goodyear racing director Greg Stucker. “That said, it also means teams have had four months to learn this car, study this package and improve their cars. The challenges Atlanta presents now have not changed since the last race in March, and with repaving and increasing incline, the smooth track surface will not naturally wear tires at all.Tire wear and heat dissipation are important in racing, because as the tire wears , it sheds rubber, which helps keep the tire cooler and performing at a more optimal level.We have specifically designed our tires for Atlanta to perform in these low wear conditions, both with the formulation tread compounds and tread depth.
Notes – Cup teams returning to Atlanta in March tire setup: After switching to an 18-inch bead diameter tire for 2022, NASCAR Cup teams will run a different tire setup than the Xfinity Series in Atlanta this week. . . both of these tire codes debuted in Atlanta in March. . . it is the only track on which these teams are programmed to perform either of these two codes. . . To prepare for 2022 and the switch to 18-inch tires, Goodyear organized a tire test in Atlanta on January 5 and 6 with Kurt Busch, Chris Buescher and Ross Chastain. . . with this 18-inch tire and its lower profile sidewall, NASCAR Cup cars will not use inner liners in any of their tires in 2022.
NASCAR Xfinity Series — Race #17 – 163 laps / 251 miles
Atlanta Motor Speedway (1.54 mile oval) – Hampton, Ga.
Quick facts for July 8 and 9, 2022

Recommended minimum inflation: Left Front — 19 psi; Left Rear – 19 psi; Right Front — 52 psi; Right Rear – 48 psi
Notes – Second race in Atlanta on this tire setup for Xfinity cars: Being on 15-inch bead diameter tires, the NASCAR Xfinity Series teams will use a different tire setup than the Cup Series in Atlanta this weekend. . . it’s the same tire setup those teams raced in Atlanta in March. . . in addition to this race, Goodyear held a tire test for Xfinity cars in Atlanta on January 4 (Justin Allgaier, Ty Gibbs and Riley Herbst). . . As on all NASCAR ovals over a mile in length, Xfinity teams are required to perform one-liners in all four tire positions in Atlanta. . . the air pressure in these inner liners should be 12-25 psi higher than the outer tire.
NASCAR Camping World Truck Series – Race #15 – 67 laps / 151.29 miles
Mid-Ohio Sports Car Course (2,258 mile road course) – Lexington, Ohio
Quick Facts for June 8-9, 2022
Tire: Goodyear Eagle 15-inch Road Course radials
Set limits: 5 sets for the event
Tire code: D-6122 (same on all four tire positions)
Tire Circumference: 2,240 mm (88.19 in)
Recommended minimum inflation: Left Front — 22 psi; Right Front — 20 psi; Left Rear – 17 psi; Right Rear – 17 psi
Notes – Truck Series debuts in Mid-Ohio on the COTA/Sonoma tire: This is the first race at Mid-Ohio for NASCAR Camping World Truck Series teams after the Xfinity Series has raced there for the past eight seasons. . . As with all NASCAR road courses, truck teams will use the same tire on all four tire positions at Mid-Ohio. . . these teams have already used this tire at COTA and Sonoma earlier this season. . . As with all NASCAR road courses, teams will not use inner liners in their tires at Mid-Ohio.
Wet Weather Tires – White Letter Tires Available: Goodyear will bring its wet-weather radial tires to Truck Series teams in Mid-Ohio, if NASCAR decides conditions warrant. . . Trucks will have 4 sets of wet tires for their event, with a maximum of 3 sets for the race. . . Truck teams last raced in the wet at COTA in 2021. . . in addition to the obvious difference in a tread pattern from Goodyear’s dry weather “slick” tires, the letters “Goodyear” and “Eagle” on the sidewalls of wet weather tires are white, not yellow standard.
