Breakdown of Goodyear tires being used at repaved, reconfigured Kentucky

Leave a comment

This weekend’s action at Kentucky Speedway is the first race weekend at the 1.5-mile track since it was repaved and reconfigured in Turns 1 and 2 from 14 to 17 degree banking.

As a result of a two-day tire test on June 13-14 the Sprint Cup Series will be running a different right-side tire than the Xfinity and Camping World Truck Series. All three series will use the same left-side tire.

Sprint Cup Tire Info

Tire Codes: Left-side — D-4688; Right-side — D-4712

Tire Circumference: Left-side — 87.56 in. (2,224 mm); Right-side — 88.50 in. (2,248 mm)

Minimum Recommended Inflation: Left Front — 25 psi; Left Rear — 25 psi; Right Front — 54 psi; Right Rear — 50 psi

Sprint Cup teams used this left-side tire code  earlier this year at Las Vegas Motor Speedway. This is the first time running this right-side tire, which features the same construction as the right-side tire used at Michigan International Speedway. It is a single compound tire with the same compound that was run on the inboard two inches of Michigan’s multi-zone tread right-side.

During the June tire test, enough blistering was discovered on tires that Goodyear’s Greg Stucker, director of race tire sales, said “we needed to react.’’

After a practice crash at Daytona last weekend, Kyle Busch expressed frustration with the tires Goodyear has provided this year, saying all four of his tires blistered after 23 laps at Kentucky during the test.

“We’ve seen it at Charlotte, we’ve seen it at Michigan, we’ve seen it at Las Vegas,” Busch said. “We’ve been there and done that. That’s why all of us drivers are so adamant to not repave these facilities for as long as we possibly can. I just don’t know with what we’ve got for (this) week if we’re going to see an outstanding race like we have in the past on the old surface.’’

Sprint Cup teams also will receive all of their tires at the same time this weekend. They typically receive their practice and race tires separately. This is being done so teams can scuff their race sets during practice by running four or five laps on those tires.

Teams will be allowed six sets of tires for practice and qualifying and 10 sets for the race. Teams can carryover a set from practice to the race.

Xfinity/Camping World Truck Series tire info

Tire set limits: Xfinity: nine sets for the event; Camping World Truck Series: seven sets for the event

Tire Codes: Left-side — D-4688; Right-side — D-4690

Tire Circumference: Left-side — 87.56 in. (2,224 mm); Right-side — 88.46 in. (2,247 mm)

Minimum Recommended Inflation: Left Front — 25 psi; Left Rear — 25 psi; Right Front — 54 psi; Right Rear — 50 psi

Right-side tire incorporates Goodyear Racing’s multi-zone tread technology, which features two distinct tread compounds — one for endurance and heat resistance on the inboard two inches of the tread and one for traction on the outboard 10 inches.

Kevin Harvick’s rear tire changer sidelined by cancer treatment

BRISTOL, Tenn. — Daniel Smith, rear tire changer for Kevin Harvick’s team, left a hospital Saturday afternoon after surgery this week as part of his cancer treatment.

Smith, who had the planned surgery Thursday, told NBC Sports through a team spokesperson that he should be back in four to six weeks. The Cup playoffs begin in four weeks at Las Vegas Motor Speedway.

It was shortly before the Bristol night race last year that doctors discovered Smith had testicular cancer. He spent the day before that race undergoing scans, blood work and other tests to determine if the cancer had spread. Doctors found that the cancer had infected two lymph nodes in his lower abdomen and also saw a spot on his lung that was concerning.

Two days after last year’s Bristol night race, Smith had surgery to remove the tumor in his testicle. After a few weeks to heal, he began chemotherapy treatments. Each round consisted of one week in a hospital and two weeks of recovery. He had four rounds (12 weeks) of treatments. Smith returned to the track to watch Harvick compete in the championship race in Miami last year and then was back to changing tires at Daytona in February.

Thursday’s surgery is expected to be the final one Smith needs. Tonight’s race (7:30 p.m. ET on NBCSN) is the first he’s missed this season. He stated through a team spokesperson that he walked a mile in the hospital Friday and again on Saturday before his release.

Harvick, who won last weekend at Michigan, starts eighth in tonight’s race at Bristol Motor Speedway.

Matt DiBenedetto focused on winning as he looks for 2020 ride

Leave a comment

BRISTOL, Tenn. — Looking for a ride for next season, Matt DiBenedetto enters tonight’s Cup race at Bristol Motor Speedway focused on one goal.

“I want to win in Cup,” says the driver whose family moved from California to North Carolina when he was a teen to help his racing career, who ran start-and-parks at one time in the Xfinity Series to keep in the sport and who has 13 races left in what is the best ride of his five-year Cup career.

DiBenedetto found out this week that he would not return to Leavine Family Racing after this season. DiBenedetto said that “I don’t want to say I was blindsided” but said he held out hope that “my performance behind the wheel (would) do the talking and hope that that would prevail over everything.”

Instead, business matters prevailed. With Erik Jones near an extension to remain at Joe Gibbs Racing — keeping all four driver spots there filled — Toyota and JGR needed a place to move Christopher Bell from the Xfinity Series to Cup. Leavine Family Racing’s alliance with JGR makes it the natural spot for Bell. While Bell said this week nothing is set, all signs point to him driving the No. 95 car next year.

Despite his disappointment, DiBenedetto remains grateful to Leavine Family Racing for the chance to run the No. 95 this year.

“I want everyone to know, fans especially and social media and stuff, is to be easy on our team and Toyota and (Joe) Gibbs and everything because they’re all still great people and they gave me this opportunity,” he said. 

Still, about a year after DiBenedetto left his ride with Go Fas Racing and unsure of where he’d land, he’s again looking for a ride for the upcoming season.

“I don’t want to retire yet because I’m only 28 years old,” said DiBenedetto, who starts seventh in tonight’s race (7:30 p.m. ET on NBCSN). “Just getting started, but I want to win in the Cup Series. That’s what I’ve said and that’s my goal. I’m here to keep on climbing the ladder, not go backwards.”

As for what he might do next year, he’s not sure.

“I have no irons in the fire per se, yet, but this all just happened just this week,” he said.

One question is if it might be possible for him to drive for Joe Gibbs Racing’s Xfinity program — DiBenedetto made his Xfinity debut with JGR in 2009 as a development driver and he will drive the team’s No. 18 Xfinity car in the upcoming race at Road America.

“I don’t think there is that opportunity or as of now, there’s not,” he said. “Not that I’m aware of. I’ve talked to the Toyota folks and stuff and I don’t foresee any opportunities within the camp, I don’t think. Just going to have to really pursue everything, but the main goal is to keep proving myself behind the wheel, which I’ve shown I’m here to win and run up front.”

Maybe something good will happen to him tonight. Bristol is where he scored his first Cup top 10 in 2016, placing sixth for an underfunded BK Racing team. He and his family celebrated that finish on pit road after the race.

Alex Bowman, who also drove for underfunded teams before working his way up to a ride at Hendrick Motorsports, is rooting for DiBenedetto to remain in Cup next season.

“I think he does a really good job in the race car,” Bowman said. “Obviously, he has shown that he continues to deserve (a Cup ride). He’ll land on his feet. Everything happens for a reason. I was pretty bummed when I lost my gig. It all ended up working out for the better.”
