Goodyear tire info for Bristol

Leave a comment

Vehicles in all three of NASCAR’s national series will carry the same tire sizes and compounds for this week’s three races at Bristol Motor Speedway.

One of the key storylines is the use of PJ1 traction compound, which is applied to a particular lane of a racetrack to give drivers an additional racing groove that is, in theory, equal to the preferred groove(s). At Bristol, the bottom lane is considered the preferred lane early in each race before the top lane becomes the preferred lane later on.

As a result, Bristol track officials will apply PJ1 to the bottom lane to give drivers an “equal” opportunity to move up or down to pass their competitors, according to this week’s Goodyear Racing media release.

“We have been working very closely with NASCAR and the tracks as the use of PJ1 has become more common on the circuit,” said Greg Stucker, Goodyear’s director of racing.  “We generally all come up with a plan, and then watch how things unfold over the weekend, also considering feedback from the drivers.

“After each day of the event, we run a friction trailer on all the lanes of the track to measure the traction level and how that changed since the beginning of that day. Then we determine if the PJ1 needs to be re-applied, whether the application patch should change at all and what the concentration level should be.

“The goal in all of this is to keep the grip level consistent throughout the weekend so teams know what racing conditions to expect. We, as an industry, are putting a lot of science behind this effort, with an end goal of improving the quality of racing for our fans.”

Here’s the tire info for all three races:

Tire: Goodyear Eagle Speedway Radials.

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; Truck: five sets for the event.

Tire Codes: Left-side — D-4860; Right-side — D-4862

Tire Circumference: Left-side — 2,223 mm (87.52 in.); Right-side – 2,251 mm (88.62 in.)

Minimum Recommended Inflation: Left Front — 20 psi; Left Rear — 18 psi; Right Front — 43 psi; Right Rear — 40 psi.

Notes: NASCAR Cup and Xfinity Series teams ran this same combination of left- and right-side tires at Bristol in April. … This is the first time NASCAR Gander Outdoors Truck Series teams have run either of these two tire codes. … Compared to what the Trucks ran at Bristol last August, this tire set-up features construction updates on both sides of the car and a compound change on the left-side. … This is the only track at which NASCAR teams will run either of these two tire codes in 2019. … Unlike on most NASCAR ovals one mile or less in length, on which teams generally do not run inner liners in their tires, teams are required to run liners in their right-side tires only at Bristol. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Goodyear tire info for Pocono, Iowa

Leave a comment

All three NASCAR premier national series are in action this weekend, with the Cup Series and Gander Outdoors Truck Series at Pocono Raceway and the Xfinity Series will be at Iowa Speedway.

Although Pocono is 2 ½ times larger than last weekend’s race at New Hampshire’s “Magic Mile,” both tracks share similarities, including relatively little banking, and teams often use left-side air pressures as a tuning tool to gain grip as the cars transition from the corners to back on the throttle onto Pocono’s long straightaways.

And because Cup teams just raced at Pocono eight weeks ago on the same tire set-up and downforce package, there will not be any changes in the tires and teams should have plenty of data from the previous June 2 race at the Tricky Triangle.

Pocono is always a challenge on both the teams and the tires,” said Greg Stucker, Goodyear’s director of racing. “Being pretty flat with long, fast straightaways and three distinct corners, teams will try to gain grip however they can, including going below our recommended air pressures, most specifically on the left-side of the car.

We integrated construction updates on both the left- and right-side tires for the June race, so since the Cup cars have already run at Pocono with this higher downforce package, they have a head start on what to expect with their set-ups this weekend.”

Cup cars will run the same combination of left- and right-side tires that they ran at Pocono in June. For the Trucks, these are two new Goodyear tire codes, featuring construction updates on both sides of the truck compared to what was run at Pocono in 2018. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tire positions at Pocono. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Here’s the Cup and Truck tire info for the weekend.

Tire: Goodyear Eagle Speedway Radials

Set limits: Cup: 3 sets for practice, 1 set for qualifying and 7 sets for the race (6 race sets plus 1 set transferred from qualifying or practice); Truck: 4 sets for the event.

Tire Codes: Left-side — D-4870; Right-side – D-4876

Tire Circumference: Left-side — 2,227 mm (87.68 in.); Right-side — 2,241 mm (88.23 in.)

Minimum Recommended Inflation: Left Front — 18 psi; Left Rear — 18 psi; Right Front — 41 psi; Right Rear — 37 psi

***************************************

As for Saturday’s Xfinity Series race at Iowa, this is the same tire set-up that the Xfinity cars previously ran at Iowa in June. The left-side tire code is the same that Xfinity teams ran at Phoenix in March.

To prepare for the 2019 season, Goodyear held a tire test with Christopher Bell, Cole Custer and Tyler Reddick at Iowa on April 16-17. Also, as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Iowa.

Here’s the Xfinity tire info for the weekend.

Tire: Goodyear Eagle Speedway Radials

Set limits: 6 sets for the event

Tire Codes: Left-side — D-4864; Right-side – D-4884

Minimum Recommended Inflation: Left Front — 16 psi; Left Rear — 16 psi;

Right Front — 36 psi; Right Rear — 34 psi

Goodyear Tire info for Chicagoland Speedway

Leave a comment

All three of NASCAR’s national series will be in action this weekend at Chicagoland Speedway, and they will all compete on updated tire combinations on the 1.5-mile track.

Compared to what was run at Chicago last year, both left and right-side tires feature construction updates to align with what is run at other speedways, while the right-side tire has also gone from a multi-zone tread tire to a single zone tread tire and will increase grip.

This tire combo was confirmed at a Goodyear test at Chicagoland on May 7. The drivers who participated in the test were Brad Keselowski, Ryan Newman and Paul Menard. As on all NASCAR ovals greater than 1 mile in length, teams are required to run inner liners in all four tire positions at Chicagoland. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

“Based on some indications we saw at our test at Chicagoland, we felt like we could bring some additional grip that will help the cars in traffic,” said Greg Stucker, Goodyear’s director of racing, in a press release. “When a trailing car closes in on a car ahead, it loses some aerodynamic downforce, so the additional mechanical grip from a more tractive right-side tire can help offset that loss. The 2019 Cup rules package has produced some good side-by-side racing so far, but based on what we saw at our test, as well as additional driver feedback, we feel like a more tractive right-side compound might help the cars throughout the field.”

Here is 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: Eight sets for the event

Truck: Seven sets for the event

Tire Codes: Left-side — D-4928; Right-side — D-4930

Tire Circumference: Left-side — 2,227 mm (87.68 in.); Right-side — 2,248 mm (88.50 in.)

Minimum Recommended Inflation: Left Front – 19 psi; Left Rear – 19 psi; Right Front – 48 psi; Right Rear – 44 psi

Goodyear tire info for Michigan (Cup, Xfinity) and Texas (Truck)

For the second consecutive week, Goodyear rubber will get another high-speed workout in Sunday’s FireKeepers Casino 400 NASCAR Cup race and Saturday’s LTi Printing 250 Xfinity race at the 2-mile Michigan International Speedway.

Meanwhile, the Gander Outdoors Truck Series will visit another high-speed track, the 1.5-mile Texas Motor Speedway, in Friday night’s SpeedyCash.com 400.

Here’s how this weekend’s tire notes shapes up at both tracks:

According to this week’s Goodyear media release about racing at Michigan, “Recent Monster Energy NASCAR Cup races at Charlotte Motor Speedway and Kansas Speedway – where passes for the lead and passing in general were up – have the NASCAR world excited about what we might see at Michigan International Speedway this weekend. With this current Cup rules package, corner speeds will be up at Michigan and tight racing throughout the field should be the order of the day. The track is still relatively smooth since it was resurfaced in 2012 so Goodyear’s tire set-up at Michigan is now aligned with what is run at another recent repave in Texas Motor Speedway.”

Added Goodyear director of racing Greg Stucker, With Michigan being a relatively recent repave, combined with the 2019 Cup rules package and drivers expected to be on the throttle all the way through the corners, we always have to be cognizant of tire heat. We combat that with the tread compounds we bring to tracks with smooth surfaces, as well as the gage or thickness of that tread that allows the tire to dissipate heat. Overall, this weekend could be a good show for the fans if it is anything like some other recent events where corner speeds have been up and there has been a lot of tight racing and passing.”

Here’s the Cup and Xfinity tire info for Michigan:

Tire: Goodyear Eagle Speedway Radials for both Cup and Xfinity.

Set limits: Cup: Three sets for practice, one set for qualifying and seven sets for the race; Xfinity: six 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 — 54 psi; Right Rear — 50 psi

Notes for Cup and Xfinity: Teams in both the Cup and Xfinity Series will run the same tire set-up at Michigan this weekend. This is the same combination of left- and right-side tires that these teams ran at Texas in March. Cup and Xfinity teams ran this same right-side tire code at Michigan in 2018. This is a different left-side than what was run on this track last year, featuring a construction change to align with other speedways. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Here’s the Trucks tire info for Texas:

Tire: Goodyear Eagle Speedway Radials

Set limits: Truck: Six 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 — 24 psi; Left Rear — 22 psi; Right Front — 52 psi; Right Rear — 50 psi

Notes for Trucks: This is the same combination of left- and right-side tires that Gander Outdoors Trucks teams ran at Texas in March. Truck teams will run this same right-side tire code at Kansas next week and this complete tire set-up at Kentucky in July. As on all NASCAR ovals greater than one mile in length, teams are required to run liners in all four tire positions at Texas. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Goodyear tire info for Pocono

Leave a comment

NASCAR returns for the first of two visits in less than two months at Pocono Raceway for this weekend’s Pocono 400 Cup race and the Pocono Green 250 Xfinity Series race.

According to this week’s Goodyear media release, “Pocono is truly a unique race track with three distinct corners, each based on another track — Turn 1 on the former Trenton Speedway, Turn 2 on Indianapolis Motor Speedway and Turn 3 on The Milwaukee Mile. Having relatively little banking, teams often use left-side air pressures as a tuning tool to gain grip as the cars transition from the high-speed straightaways to the low-speed corners. Goodyear has integrated construction updates to both the left- and right-side tires for this race, incorporating elements that have shown positive results in fundamental testing. The tread compounds on both sides of the car are the same as last year.”

Added Greg Stucker, Goodyear’s director of racing, “Pocono provides several challenges for tires and teams, being pretty flat with long, fast straightaways and three unique corners. We have to bring a tire set-up that handles those demanding conditions, perhaps most notably the corners where we need to provide grip levels more like what’s needed on a short track. This being a race with higher downforce than last year paired with the lower horsepower package, the tread compounds remain unchanged from 2018, which should help with grip as well.”

Notes – New set-up for Cup and Xfinity at Pocono: Teams in the Monster Energy NASCAR Cup and Xfinity Series will run the same tire set-up at Pocono this weekend. … These are two new Goodyear tire codes for this week, featuring construction updates on both sides of the car compared to what was run at Pocono last season. … As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tire positions at Pocono. … Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Here’s the tire info for this weekend’s races:

Tire: Goodyear Eagle Speedway Radials for both Cup and Xfinity.

Set limits: Cup: 3 sets for practice, 1 set for qualifying and 7 sets for the race; Xfinity: 6 sets for the event.

Tire Codes: Left-side — D-4870; Right-side – D-4876

Tire Circumference: Left-side — 2,227 mm (87.68 in.); Right-side — 2,241 mm (88.23 in.)

Minimum Recommended Inflation: Left Front — 18 psi; Left Rear — 18 psi; Right Front — 41 psi; Right Rear — 37 psi
