In the “zone”: New Goodyear tires making debut at Atlanta

0 Comments

This weekend at Atlanta Motor Speedway, NASCAR Sprint Cup squads are using a new right-side tire from supplier Goodyear that combines two separate compounds across its surface.

Dubbed “zone tread” technology by Goodyear, the tire utilizes a harder inside shoulder for heat resistance and a softer outside portion for added grip.

The inside compounds are the same as the one used at Michigan International Speedway this year, while the outside features a compound that has been used in recent events at Atlanta.

The “zone tread” tires were used as part of a 13-team test at AMS earlier this month and have been tested at other tracks. But Sunday night’s Cup race will provide the toughest task to date for the new tires – 500 miles on one of NASCAR’s fastest and most abrasive circuits.

“Atlanta is one of our biggest challenges from a tire perspective,” Goodyear general manager of worldwide racing Stu Grant told The Associated Press. “The abrasive surface causes extremely high wear, while the length and layout promote very high speeds.”

“What we’ve done here is take a specific rubber compound and limit the application to the inside shoulder, and then have a more tractive compound across the rest of the tread.”

Goodyear has utilized the “zone” concept on its passenger tires, but Sunday’s Advocare 500 will mark its first use in NASCAR competition.

When asked about his thoughts on the new tire, Stewart-Haas Racing driver Ryan Newman felt that Goodyear was using “a common sense approach.”

“Here at Atlanta, it’s the best worst-case scenario for that because it is the toughest track we have on tires,” he said on Friday. “The strength of that zone tread tire is the durability side of it. The biggest part of the durability side of what we do is the inside shoulder of the right front tire.

“I think, all that being said, I hope there are no issues. The reason they’re doing that is so there won’t be any issues because this new [Gen-6] car is definitely the most challenging we’ve had on tire durability.”

DAYTONA BEACH, Fla. — The 2023 Rolex 24 at Daytona overall results were all streaks: two consecutive victories in the endurance classic for Meyer Shank Racing and three in a row for Acura.

And Helio Castroneves became the second driver to win three consecutive Rolex 24s and the first to win in three straight years (Peter Gregg won in 1973, ’75 and ’76; the race wasn’t held in ’74 because of a global oil crisis).

Starting from the pole position, Tom Blomqvist took the checkered flag in the No. 60 ARX-06 that led a race-high 365 of 783 laps with co-drivers Castroneves, Simon Pagenaud and Colin Braun.

Meyer Shank Racing now has two Rolex 24 victories and the 2022 championship since entering the premier prototype category of the IMSA WeatherTech SportsCar Championship in 2021.

“I think what’s so special about this team is we are a small team compared to some of our opponents, but the atmosphere, the way we work, enables people to get the best out of themselves, and I think that’s why we’re such high achievers,” Blomqvist said. “I think there’s no egos. It’s a very open book, and that just enables each and every one of us to reach our potential. I think that’s why we’ve achieved so much success in really a short time at this level of competition.”

It’s the 16th IMSA victory for MSR.

The 61st running of the Rolex 24 at Daytona marked the debut of the Grand Touring Prototype category that brought hybrid engine technology to IMSA’s top level.

In other categories:

LMP2: James Allen passed Ben Hanley on the final lap and delivered a victory in the No. 55 ORECA by 0.016 seconds. It’s the second IMSA victory for Proton Competition, which last won at Sebring in 2012. It was the first Rolex 24 victory for Allen and co-drivers Gianmaria Bruni, Fred Poordad and Francesco Pizzi.

GTD Pro: Cooper MacNeil won in the last start of his IMSA career as the No. 79 Mercedes-AMG GT3 scored the first Rolex 24 at Daytona for WeatherTech Racing and the team’s fourth career victory.

MacNeil, who co-drove with Maro Engel, Jules Gounon and Daniel Juncadella, earned his 12th career victory and first at the Rolex 24.

“Winning by last IMSA race is tremendous,” MacNeil said.

GTD: The No. 27 Heart of Racing Team delivered the first Rolex 24 at Daytona for Aston Martin, which has been competing in endurance races at Daytona International Speedway since 1964. Drivers Marco Sorensen, Roman De Angelis, Darren Turner and Ian James (also the team principal) earned the victory in the English brand’s 13th attempt.

It’s also the first Rolex 24 at Daytona win for Heart of Racing, which has seven IMSA wins.

LMP3: Anthony Mantella, Wayne Boyd, Nico Varrone and Thomas Merrill drove the No. 17 AWA Duqueine D08 to victory by 12 laps for the team’s first class win in IMSA.
