Goodyear tire info for Kansas Speedway

Leave a comment

Cup and Xfinity Series team continue their respective playoffs this weekend with a visit to Kansas Speedway.

Both series will visit the 1.5-mile track with the same tire codes on each side of the car.

The left-side tire code will be new for Cup teams at Kansas. Both right and left-side tires codes are new for Xfinity Series teams at Kansas. They feature a construction update on both sides of the car and move from a multi-zone tread on the right-side to a single zone tread compound, compared to last year.

The right-side code has been used by both series this season at Kentucky, Las Vegas, Michigan and Texas.

“What we have seen Kansas over the past several races is that the track surface has weathered a bit and will wear tires,” Greg Stucker, Goodyear’s director of racing, said in a press release. “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.”

Here is the tire info for this weekend at Kansas.

Set limits: Cup: Three sets for practice, one set for qualifying and 10 sets for the race  (nine race sets plus one set transferred from qualifying or practice);

Xfinity: Seven sets for the event

Tire Codes: Left-side — D-4942; Right-side — D-4796

Tire Circumference: Left-side — 2,225 mm (87.60 in.); Right-side — 2,251 mm (88.62 in.)

Minimum Recommended Inflation: Left Front – 22 psi; Left Rear – 22 psi; Right Front — 52 psi; Right Rear — 50 psi

Cup and Gander Outdoors Truck Series teams will return to the 2.66-mile Talladega Superspeedway this weekend as the NASCAR playoffs continue.

Here is a breakdown of the Goodyear tires each series will compete on.

With Talladega being longer than one mile, teams in both series are required to use inner liners in all four tires. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Cup Series tire info

The Cup Series will run a completely different tire setup than the Truck Series.

Cup teams will run the same left-side tire code they ran at this track in April. But they’ll have a brand new right-side tire code. Compared to what was run in the spring, this right-side tire features a construction update to align it with what is run at other tracks.

Set limits: Cup: Two sets for practice, one set for qualifying and seven sets for the race (six race sets plus one set transferred from qualifying or practice)

Tire Codes: Left-side — D-4886; Right-side — D-4952

Tire Circumference: Left-side — 2,236 mm (88.03 in.); Right-side — 2,249 mm (88.54 in.)

Minimum Recommended Inflation: Left Front — 29 psi; Left Rear – 29 psi; Right Front — 50 psi; Right Rear — 48 psi

 

Truck Series tire info

Teams in the Truck Series will use the same right and left-side tire codes they used at Talladega last year.

Set limits: Truck: Four sets for the event

Tire Codes: Left-side — D-4596; Right-side — D-4752

Tire Circumference: Left-side — 2,233 mm (87.91 in.); Right-side — 2,249 mm (88.54 in.)

Minimum Recommended Inflation: Left Front — 29 psi; Left Rear – 29 psi; Right Front — 50 psi; Right Rear — 48 psi

All three of NASCAR’s national series will be competing on new tires this weekend as they race on different track surfaces.

Cup and Xfinity Series teams will be road-course racing at Watkins Glen International, and the Gander Outdoors Truck Series holds its annual race on the dirt of Eldora Speedway.

Here’s the tire info for both tracks.

Cup and Xfinity – Watkins Glen

Cup and Xfinity Series will run the same Goodyear tire code on all four tires at Watkins Glen. This is a brand new tire, featuring the same tread compounds as 2018 with just a construction update.

Watkins Glen International is a faster and less technical road course than the Cup Series’ earlier stop at Sonoma Raceway. WGI’s 2016 repave only added to that. Because of the sustained speed
 on the course, WGI requires a different tire
 set-up, and one that utilizes a more heat-resistant tread compound.

While the compound run at Sonoma is more tractive by comparison, the one run at WGI is still among the top-third in that area in Goodyear’s 2019 tire lineup.

Tire info

Set limits: Cup: Three sets for practice, one set for qualifying and five sets for the race (four race sets plus one set transferred from qualifying or practice)

Xfinity: Six sets for the event

Tire Code: D-4926 (same on all four tire positions)

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

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

 

Truck Series – Eldora

This is a new tire set-up for Truck Series teams at Eldora. Compared to the 2018 Eldora race, both this left-side and right-side tire feature a tread compound change to introduce more wear.

There are three main differences between this tire set-up and the one that Truck teams normally run on asphalt ovals. 1) these are bias ply tires, not radials, and are more compliant and able to envelope the irregularities of the dirt surface. 2) these tires have a block-style tread pattern with leading edges on the blocks to bite into the dirt surface and grooves to help evacuate the dirt, not a “slick” or smooth tread. 3) This left-side tire is significantly shorter to create more stagger between the left- and right-side tires.

Tire info

Teams will not run inner liners in their tires at Eldora.

Set limits: Four sets for the event

Tire Codes: Left-side — D-3024; Right-side — D-3026

Tire Circumference: Left-side — 85.79 in. (2,179 mm); Right-side — 88.50 in. (2,248 mm)

Minimum Recommended Inflation: Left Front — 18 psi; Left Rear – 18 psi; Right Front — 22 psi; Right Rear — 22 psi

Cup and Xfinity Series teams return to New Hampshire Motor Speedway this weekend and will compete on new right and left-side tires on the 1.058-mile track.

While the tires will feature the same tread compounds that were run at New Hampshire last year, they will have construction updates to bring this set-up in line with what is run at other tracks. This is the only track at which teams in either of these series will run these two Goodyear tire codes.

As on most NASCAR ovals 1 mile or less in length, teams will not run inner liners in their tires at New Hampshire.

According to a Goodyear press release, because of NHMS’ minimal banking, the track produces minimal load compared to more high-banked tracks. Because of that, grip needs to be generated through the compounds selected in Goodyear’s tire set-up.

Goodyear says both the left and right-side compounds run at New Hampshire are among the highest performing in its tire lineup.

Greg Stucker, Goodyear’s director of racing, cautioned teams against lowering the air pressure in their left-side tires below the minimum recommended inflation levels of 12 psi.

“Loudon has very little banking, so some teams try to enhance their level of grip by getting aggressive with their air pressures, most notably on the left-side of the car,” Stucker said in the press release. “Our recommended left-side pressures at Loudon are 12 psi, and teams have been known to drop well below that in the race.  Running below our recommendations are always a risk vs. reward proposition.  Air pressure provides structure to a tire, and running too low risks the sidewall over-deflecting early on in a run, which can lead to carcass fatigue and eventually an air loss.”

New Hampshire will treat its track surface with the PJ1 traction compound in all four turns this weekend.

Here’s the tire info for the weekend.

Set limits: Cup: Three sets for practice, one set for qualifying and nine sets for the race (eight race sets plus one set transferred from qualifying or practice);

Xfinity: Six sets for the event

Tire Codes: Left-side — D-4922; Right-side — D-4924

Tire Circumference: Left-side — 2,226 mm (87.64 in.); Right-side — 2,239 mm (88.15 in.)

Minimum Recommended Inflation: Left Front – 12 psi; Left Rear – 12 psi; Right Front – 30 psi; Right Rear – 27 psi

Goodyear tire info for Kentucky Speedway

When NASCAR teams compete at Kentucky Speedway this weekend, they will be doing so on a new tire combination for the 1.5-mile track.

Teams will run the same left-side tire code as last year at Kentucky, but they will compete on a new right-side tire.

While this is the first time these teams have run this right-side tire code at Kentucky, it has been run it at Las Vegas (Cup & Xfinity), Texas (all three series), Kansas (Cup & Truck) and Michigan (Cup and Xfinity) this season.

Compared to what was run at this track last season, this right-side tire features a compound change to bring it into line with what is run at several other tracks with relatively “smooth” track surfaces. Kentucky was repaved in 2017.

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

“Over the past several years, we’ve had quite a few tracks that have been resurfaced, including Kentucky Speedway,” said Greg Stucker, Goodyear’s director of racing, in a press release.  “We held a test at another recent repave at Texas Motor Speedway last August, and the goal of that session was to try to introduce more wear at some of these tracks with non-abrasive surfaces like Texas and Kentucky.  We found something that has worked well, so we’ve brought this same right-side out several times with good results.  It also benefits the teams by being able to run the same tire code at different tracks so they can remove that variable from the equation.”

Here is the tire info for the weekend.

Set limits: Cup: Three sets for practice, one set for qualifying, eight sets for the race (seven race sets plus one set transferred from qualifying or practice);

Xfinity: Seven sets for the event

Truck: Five sets for the event

Tire Codes: Left-side — D-4798; Right-side — D-4796

Tire Circumference: Left-side — 2,227 mm (87.68 in.); Right-side — 2,251 mm (88.62 in.)

Minimum Recommended Inflation: Left Front – 22 psi; Left Rear – 22 psi; Right Front – 52 psi; Right Rear – 50 psi
