RULES PACKAGE

This weekend’s race will feature the 2019 rules package with no aero ducts and a tapered-spacer engine generating a targeted 750 horsepower.

Each team will be provided with three sets of Goodyear Eagle Speedway Radials for practice, one set for qualifying and eight sets for the 248.52 mile race (seven sets plus one set transferred from qualifying or practice).

Goodyear will bring a traditional road course tire to the Roval, although there is a big difference in the air pressure recommendations compared to what is run at other road courses like Watkins Glen and Sonoma. Those two courses are run in a clockwise direction for the most part with a majority of right-hand turns. The Roval is run counter-clockwise, which makes it a majority left-hand course.

“While the course has gone through several changes since it was first laid out in late 2017, the fact remains that we treat the Roval as a road course from a tire perspective,” said Greg Stucker, Goodyear’s director of racing. “The Roval is definitely unique in the NASCAR world, and requires us to be aware of many factors. Similar to other road courses, we have to bring a tire and recommend air pressures that reflect the hard braking and acceleration on and off the corners. The main difference is the use of the oval as part of the course, where loads on the right-front will be higher than any other corner of the car.”

RULES PACKAGE

The race at Dover will feature the 2019 rules package with no aero ducts and a tapered-spacer engine generating a targeted 750 horsepower.

Each team will have three sets of tires for practice, one set for qualifying and 10 sets for the 400-mile race — nine race sets plus one set transferred from qualifying or practice.

Steep banking at tracks such as Dover creates higher loads specifically on the right-front tire. Due to that, Goodyear will be working with teams to stress the importance of set-ups as well as air pressures on the right-front tire. Goodyear performed additional simulation work for this track to give teams the most current information on how air pressure affects both durability and performance.

“When we went to Bristol for the second time in 2019, we saw exactly how many gains these teams have made with this package since the first race there in the spring, and we expect the same at Dover this week,” Greg Stucker, Goodyear’s director of racing, said. “Right-front durability at Dover is always on our radar because of the speeds and loads generated by these cars in the high-banked corners. … We certainly understand that in the teams’ efforts to gain as much grip as possible, being aggressive on air pressures is one of the tools they use.”

RULES PACKAGE

The race at Talladega will feature the 2019 rules package with aero ducts and a tapered-spacer engine generating a targeted 550 horsepower.

Each team will have two sets of Goodyear Eagle Speedway Radials for practice, one set for qualifying and seven sets for the 500-mile race (six race sets plus a set transferred from qualifying or practice).

Unlike its fellow superspeedway, Daytona International Speedway, Talladega features a more abrasive surface that increases wear on tires that affects team strategies throughout the race.

“While we will see some pit strategy at Talladega, it is a track that actually wears tires a bit, especially when compared to Daytona,” said Greg Stucker, Goodyear’s director of racing. “Depending on where teams are running and who they are working with, they can take four tires, or two, or fuel only to gain some track position.”

RULES PACKAGE

The setup for Kansas will follow the 2019 rules package with aero ducts and a tapered-spacer engine generating a targeted 550 horsepower.

Each team is allowed three sets of Goodyear Eagle Speedway Radials for practice, one set for qualifying and 10 sets for the race (nine sets plus one transferred from practice or qualifying).

Last repaved in 2012, the weathering track surface has led to slightly increased lap times and tire fall-off. Throughout the race, teams will likely opt for four-tire stops to maintain balanced grip entering and exiting the corners.

“We have a new left-side tire for Kansas, with a construction update that we have been rolling into most tracks over this season, paired with a right-side tire the teams have a good notebook on after having run it seven times already this year,” said Greg Stucker, Goodyear’s director of racing. “What we have seen at Kansas over the past several races is that the track surface has weathered a bit and will wear tires. This right-side tire is also designed to lay rubber, so that will lead to the track changing throughout the weekend as multiple racing grooves are created.”

TRACK DETAILS

Kansas Speedway is a 1.5-mile tri-oval with an asphalt surface. The track features 17-20 degrees of variable banking in the turns, 9-11 degrees of variable banking on the frontstretch and 5 degrees of banking on the backstretch.

The inaugural race at the track was won by NASCAR Hall of Fame driver Jeff Gordon on Sept. 30, 2001.

RULES PACKAGE

The Martinsville race setup will utilize the 2019 rules package used at short tracks throughout the season. Cars will use a tapered-spacer engine that generates a targeted 750 horsepower without being fitted with aero ducts.

Teams will have three sets of Goodyear Eagle Short Track Radials for practice, one set for qualifying/start of race and nine sets for the race (eight race sets plus one transferred from qualifying or practice).

As we move deeper into the fall season, rubbering in the concrete corners may prove to be a challenge. The ability for the track to take on rubber is vital in improving the racing and opening up multiple grooves on the track. With a unique design, Goodyear has developed a right-side tread compound to counter the expected cooler temperatures.

“It’s getting later in the fall and we are likely to have cloudy conditions and temperatures in the 60-degree range at Martinsville this week, so track temps will be low, making it more difficult for the track to take rubber,” said Greg Stucker, Goodyear’s director of racing. “Because of the time of year we run at Martinsville, we’ve worked hard over the past several years to come up with a tread compound that will lay rubber in the concrete corners, even in cool temperatures.

RULES PACKAGE

Texas will see cars modeled with aero ducts and use a tapered-spacer engine that is targeted to generate around 550 horsepower. Teams will be allowed three Goodyear Eagle Speedway Radials for practice, one set for qualifying and 10 sets for the race (nine new race sets plus one transferred from practice or qualifying).

The newly repaved and therefore smoother surface is more difficult for tires to lay down rubber and create additional groves early in the race. The use of PJ1 will be instrumental in providing grip on new areas of the track.

“Since its repave a couple years ago, Texas is one of the more ‘smooth’ surfaces we race on in NASCAR,” said Greg Stucker, Goodyear’s director of racing. “The right-side tire we bring to Texas is the same one we’ve run at other tracks where we want to introduce wear or rubber-in the track. The track will also apply PJ1 to the surface this weekend to help create a second groove and give drivers options.”

RULES PACKAGE

Teams will run the 2019 rules package used at short tracks throughout the season, equipped with a 750 horsepower tapered-spacer engine. Cars will not have aero ducts.

Each team will be provided three sets of Goodyear Eagle Speedway Radials for practice, one set for qualifying and nine sets for the race (eight race sets plus one set transferred from practice or qualifying).

The unconventional length of the track and the wide exit in Turn 1 make high top-end speed an emphasis for teams. However, the unique style of racing also requires additional focus on handling in frequent three-wide and potentially four-wide scenarios on the backstretch.

“This being the NASCAR Cup Series’ last short track race of the season, it is the final time we will run this high downforce/high horsepower package,” said Greg Stucker, Goodyear’s director of racing. “There’s really no other track on the circuit that is quite like Phoenix. Its unique configuration is relatively flat, but it also races more like a speedway than a traditional short track.”

RULES PACKAGE

Cars at Homestead-Miami will run a 550 horsepower tapered-spacer engine and be equipped with aero ducts. After the race at Atlanta, the original 2019 rules package was updated to include aero ducts at Pocono, Darlington and for the championship in Miami.

Teams will have three sets of Goodyear Eagle Speedway radials for practice, one set for qualifying and 12 sets for the 400-mile race (11 race sets plus one transferred from practice or qualifying). With 12 sets of race tires, tire management will be extremely important to teams throughout the entire race. Maintaining track position while managing increased tire fall-off will most likely make pit stops a vital factor in deciding this year’s champion. Race fans should expect to see four tire stops all day.

“Homestead is one of the highest tire wear tracks that we have on the NASCAR circuit,” said Greg Stucker, Goodyear’s director of racing. “We have a new tire set-up for Homestead, and it is the same one we ran at both Chicagoland and Darlington earlier this season. The compounds we will be running provide plenty of grip, but also offer the endurance needed on Homestead’s track surface. These high wear tracks put on some of our best races, and the past several years at Homestead have proven that.”
