Goodyear tire info for NASCAR at Daytona International Speedway

Leave a comment

Goodyear has announced the tires that will be used by all three of NASCAR’s national series during Speedweeks at Daytona International Speedway.

While all three series will use the same type of tire compounds, only the Cup and Xfinity Series have raced on it before.

They first used the new compounds in July at Daytona. The previous tire compound used at Daytona had been introduced in 2013.

For the Trucks, compared to what was run at Daytona last February, there is a compound change to both the left and right-side tires to give the trucks more grip.

As on all NASCAR ovals greater than 1 mile in length, teams are required to run inner liners in all four tire positions at Daytona. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

When NASCAR Cup and Xfinity Series teams take to Watkins Glen International this weekend they will be racing on the same type of tire.

This will be the first time this tire code has been used and this is the only track it is used at. Compared to what was run at Watkins Glen last year, this tire features a compound change
to give the cars more grip. As on all NASCAR road courses, teams will not run inner liners in their tires at Watkins Glen.

Here’s the tire info:

Set limits: Cup teams will receive three sets for practice, one set for qualifying and five for Sunday’s race.
Xfinity series teams will have six sets for the entire weekend.

Tire Code: D-4716 (same on all four tire positions)

Tire Circumference: 88.23 in. (2,241 mm)

Minimum Recommended Inflation: Left Front — 26 psi; Left Rear — 21 psi; Right Front — 24 psi; Right Rear — 21 psi

With this weekend being a road course, teams will also have rain tires on hand in case things get wet.  Goodyear will bring its wet weather radials (D-4215) for both series.

Wunderground.com predicts chances of overnight rain and thunderstorms Friday night. Chances of rain do not go above 15 percent after 7 a.m. ET on Saturday.

NASCAR’s West Coast Swing ends this weekend at Auto Club Speedway in Fontana, California. The 2-mile speedway is only the second track larger than 1.54-miles that NASCAR has visited so far this season.

NASCAR Cup and Xfinity Series teams will use the same tire combination this weekend. The combination is unique in its use for Auto Club Speedway. Xfinity teams will have a different minimum recommended inflation on their left-front tires.

Cup team will be allowed four sets for practice, one set for qualifying/start of race and 10 sets for race. Xfinity teams will be allowed eight sets for the entire weekend.

Here is the tire info:

Tire Codes: Left-side — D-4650; Right-side — D-4658

Tire Circumference: Left-side – 87.56 in. (2,224 mm); Right-side – 88.39 in. (2,245 mm)

Minimum Recommended Inflation (Cup): Left Front – 19 psi; Left Rear – 19 psi; Right Front – 45 psi; Right Rear – 42 psi

Minimum Recommended Inflation (Xfinity): Left Front – 21 psi; Left Rear – 19 psi;Right Front – 45 psi; Right Rear – 42 psi

This is the same combination of left and right-side tires Cup teams ran in this race last year. Xfinity teams ran this left-side tire at Auto Club in 2016, but this is their first time running this multi-zone tread right-side tire. Cup teams also ran this left-side tire at Indianapolis and Darlington last season, while Xfinity teams ran it at Pocono and Indianapolis.

This right-side code, being a multi-zone tread tire, features two distinct tread compounds on the same tire — one for endurance and heat resistance on the inboard two inches of the tread and one for traction on the outboard 10 inches. Like with all NASCAR ovals greater than 1 mile in length, teams are required to run liners in all four tire positions at Auto Club. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Paul Menard crew member unharmed after ‘fluke’ tire incident in pits

2 Comments

FORT WORTH, Texas – Mason Jennings, a tire specialist on the No. 27 of Paul Menard, was unharmed and had ringing in his ears after a tire appeared to explode during a Menard pit stop in the AAA Texas 500 at Texas Motor Speedway.

But according to a Goodyear tire official, the tire did not explode. The accident was a “fluke,” a result of the tire’s inner liner slipping completely off the wheel. Menard was in the pits after spinning in Turns 3 and 4 on Lap 143.

“When a car spins it generally flat spots the tires, which is exactly what happened here,” said Greg Stucker, Goodyear’s director of race tire sales. “It flat spotted both front (tires). The damage that was done to the left front as he drove around the race track looked like it partially unseated the inner liner. So it was actually the inner liner that let go on pit road. It wasn’t the tire itself. The tire was already down.”

Jennings was taken to the infield medical center but released.
