NASCAR’s Pemberton: Fontana tire failures not a Goodyear problem

4 Comments

After today’s Auto Club 400 at Auto Club Speedway was marked by a string of tire failures, NASCAR vice president of competition Robin Pemberton told reporters afterwards that the blame for the failures should not be put at Goodyear’s feet.

With seven laps to go, race leader Jimmie Johnson lost his chance to win when the left-front tire went down on his No. 48 Hendrick Motorsports Chevrolet. Three more tire failures ensued in the next five laps to set up the green-white-checkered finish of the race, which was won by Kyle Busch.

Multiple other drivers including Kevin Harvick (who lost two left rear tires alone), Dale Earnhardt Jr., Greg Biffle, Carl Edwards, and Danica Patrick also suffered tire failures at some point during today’s race.

But Pemberton believes that aggressive setups on the part of the teams were at the root of those problems.

“Over the past few years, we’ve been on a path to add mechanical grip, give more options to the teams,” he explained. “We’ve opened up camber rules for grip in both the front and the rear of the car. They have a lot of tools to use if they choose to do so.

“But the tires weren’t wearing. At some parts of the race, the tires were abused a little bit, so I guess that’s why the failures.”

Pemberton also said the teams asked for “aggressive tires” from Goodyear that they would need to manage and figure out how to get the most out of. Additionally, he said that some teams were running Goodyear tires with as low as 14 pounds of air, well below their recommended cold tire reading of 22 pounds.

Nonetheless, some of the drivers had different emotions on the subject following the race at Fontana.

Jeff Gordon was able to inherit the lead from Johnson after his tire failure, but had fallen farther behind Johnson prior to the incident because of a tire issue on his own car.

“I hate Goodyear was not prepared today for what happened,” said Gordon, who wound up finishing 13th after losing out badly on the G-W-C restart. “They are so good at what they do and that is just uncalled for. We were having a tire issue there on that last long run and I just backed off.

“When I saw the No. 48 had issues, I was just hoping we would make it to the end and I was just going as slow as I possibly could trying to maintain the lead and cars were just blowing tires left and right all around me.”

But neither his teammate, Dale Earnhardt Jr., or third-place finisher Kurt Busch would pin the blame on Goodyear.

Earnhardt, who finished, 12th, felt that ACS’ bumpy layout – particularly its backstretch – had more than a little to do with the failures.

“To be honest with you, the back straightaway is very rough and I think the tire can’t handle the load that it goes through on that back straightaway,” he said. “And it’s just tearing the tire up where the sidewall and tread are put together.

“…I feel bad for Goodyear. I think the tire is fine. I like the tire. It’s just those bumps. If you watch the cars go through there in slow motion, it shouldn’t be like that.”

Kurt Busch also noted NASCAR’s decision to give the teams more leeway in determining their mechanical set-ups.

“By no means is this a problem for Goodyear,” he said of the situation. “It’s just a thumbs-up for NASCAR for allowing teams to get aggressive in all areas.”

Juncos Racing continued to bolster its entries in the Pro Mazda Championship Presented by Cooper Tires by signing Carlos Cunha to pilot a third Juncos Pro Mazda entry for 2018. Cunha, who finished third in the 2017 Cooper Tires USF2000 Championship Powered by Mazda season on the back of seven podium finishes, joins Rinus VeeKay and Robert Megennis in Juncos’ Pro Mazda lineup for 2018.

Cunha previously tested with the team at Mid-Ohio Sports Car Course in October and joined Juncos for the Chris Griffis Memorial test at the Indianapolis Motor Speedway in November, testing cars for both the Pro Mazda and Indy Lights Presented by Cooper Tires teams.

“It’s great to become a part of Juncos Racing,” said the 18-year-old Cunha. “I am really excited to start the 2018 season with Juncos Racing. This fall we did some testing together and from there I was able to see how focused everyone on the team is and I even felt like I became a part of their family in no time. I am confident we will get great results together next year and I look forward to learning and growing more with the team. It will be a huge pleasure and also a great responsibility to carry the number one on my car, thanks to (2017 Pro Mazda champion Victor Franzoni) and I hope to deliver it back to the team at the end of the year!”

Team owner Ricardo Juncos added, “We are excited to add Carlos to our Pro Mazda lineup. From the moment we started testing with him in early October, we knew he would be a great fit for our team. Carlos has been very quick in testing and even had an impressive showing in the Indy Lights car at the Chris Griffis test back in October. He had a great run this past season in the Pro Mazda series and we are confident he will carry that momentum into the 2018 season.”
