Goodyear bringing new tire to Kentucky

Leave a comment

NASCAR teams will have a different right-side Goodyear tire this week at Kentucky Speedway. The change was made after the track added a four-inch layer of asphalt after last year’s race. The track had been repaved and reconfigured before the 2016 race.

The new right-side tire, which will be used by Cup, Xfinity and Truck teams this week, features a compound change to provide more grip and wear. The left-side tire remains the same. The combination was confirmed in a test May 9-10 with Kurt Busch, Austin Dillon, Erik Jones and Jamie McMurray.

Tire: Goodyear Eagle Speedway Radials

Set limits:

Cup: 4 sets for practice, 1 set for qualifying and 8 sets for the race

Xfinity: 8 sets for the event

Truck: 7 sets for the event

Tire Codes:

Left-side — D-4688; Right-side — D-4750

Tire Circumference:

Left-side — 87.56 in. (2,224 mm); Right-side — 88.58 in. (2,250 mm)

Minimum Recommended Inflation:

Left Front — 25 psi; Left Rear — 25 psi

Right Front — 54 psi; Right Rear — 50 psi

Notes: Teams in all three NASCAR national series in action at Kentucky this week will run the same tire set-up. … Teams will run the same left-side tire code (D-4688) as last year at Kentucky, but with a new right-side code (D-4750). … Compared to what was run last season, this right-side tire features a compound change to give more grip and introduce more wear. … This tire set-up came out of a Goodyear test at Kentucky on May 9-10. … Drivers participating in that test were Kurt Busch, Austin Dillon, Erik Jones and Jamie McMurray. … 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. … The goal of that May test was both to tune the grip to the fresh surface as the Cup and Xfinity Series go to lower downforce packages and induce more wear on a new surface that won’t easily wear tires and take on rubber.  The reason why the latter is important is two-fold: (1) when tires wear it often puts a premium on tire management and maintaining the car’s balance over the course of a full fuel run, and (2) when a track takes rubber, it creates multiple racing grooves and creates conditions for better racing.

NASCAR America: Should penalty for failing inspection be more severe?


After 13 cars failed qualifying inspection last Friday at Auto Club Speedway, NASCAR America’s analysts addressed the current state of rules that resulted in all thirteen teams not getting to make a qualifying attempt.

While Kyle Busch said the issues are “not that big deal,” especially with the new scanning system still in its infancy, Jeff Burton disagrees. Burton points to how much engineering has become involved in the sport and trying make cars better with NASCAR’s rules.

“It’s snowballed into this great big bag of rules,” Burton said. “We have all these rules that the teams have forced NASCAR to create. I don’t know the way out of it. There’s two ways to do it. You make the penalties harsher, with the theory being they won’t do it if the penalty is so harsh, or you have less rules. The problem is if you have less rules you’re going to have more cars that aren’t within those rules as they are.”

After the issues in Cup qualifying, NASCAR told Xfinity Series teams on Saturday that any team that did not attempt a lap in qualifying would start from the rear of the field and be required to serve a pass-through penalty once the green flag waved.

“It is a mess, but I disagree with Kyle (Busch), it is a big deal,” Burton said, citing fans who don’t get to see their favorite driver qualifying. “That’s not good. That’s not good for sponsors, that’s mainly not good for mainly race fans. If race fans tune in and their guy isn’t on track, why are they going to tune in next week? They deserve to see their guy on track. It’s got to get fixed.”

NASCAR announced Monday that inspection this weekend at Martinsville Speedway would take place after qualifying and would also serve as pre-race inspection.

Jarrett, who said there are too many rules, agreed with Burton.

“The only way of fixing this is making the penalty so severe that these teams aren’t going to take any chances,” Jarrett said.

Landon Cassill will drive the No. 00 for StarCom Racing in the next two races, Martinsville and Texas, the team announced Monday.

Cassill replaces Jeffrey Earnhardt. StarCom Racing and Earnhardt parted ways after Sunday’s race at Auto Club Speedway.

Sunday’s race at Martinsville Speedway will mark Cassill’s first Cup race of the year. The 28-year-old has 259 career Cup starts and a career-best finish of fourth at Talladega in October 2014. He drove for Front Row Motorsports the past two seasons but was not retained after last year.

Cassill’s sponsor the next two races will be the United States First Responders Association, a non-profit, professional and social network of fire, EMS, rescue, law enforcement and military personnel, as well as civilian support teams.

StarCom Racing was privileged to acquire a new partnership with USFRA and Landon Cassill behind the wheel,” said Derrike Cope, team manager, in a statement. “I’m optimistic that his knowledge and experience will only help our efforts as well as the growth of our team.”

Said Cassill in a statement: “I love working with new teams. I feel like that is one of my strengths. StarCom Racing looks like they are in it for the long haul, and I am thrilled to be a part of it.”

Hendrick Motorsports withdraws appeal of Phoenix penalties against No. 9 team

Hendrick Motorsports has withdrawn its appeal of penalties against Chase Elliott‘s N0. 9 team from last weekend’s race in Phoenix, NBC Sports confirmed.

NASCAR found a L1 infraction on Elliott’s car in the rear-suspension after the race at ISM Raceway.

NASCAR stated that the team’s truck trailing arm spacer/pinion angle shim mounting surfaces must be planar and in complete contact with corresponding mating surfaces at all points and at all times.

NASCAR fined crew chief Alan Gustafson $50,000, suspended car chief Josh Kirk two races and docked Elliott 25 points and the team 25 owner points. Elliott’s third-place finish in the race will not count toward any tiebreakers.

Following Sunday’s race at Auto Club Speedway, where Elliott finished 16th, he is 21st in the point standings.
