Goodyear tire info for this weekend at Kansas Speedway

Leave a comment

With NASCAR travelling to Kansas Speedway this weekend, the two series competing there will two different tire arrangements.

Cup Series

Goodyear brings two tire codes that are new to Kansas this week. The following tire set up was verified at a test at Kansas last October that included  Jimmie Johnson, Joey Logano, Danica Patrick and Martin Truex Jr.

Teams will be allowed four sets for practice, one set for qualifying and eight for the Go Bowling 400.

Tire Codes: Left-side — D-4698; Right-side — D-4720

Tire Circumference: Left-side — 87.44 in. (2,221 mm); Right-side — 88.66 in. (2,252 mm)

Minimum Recommended Inflation: Left Front — 22 psi; Left Rear — 22 psi; Right Front — 54 psi; Right Rear — 50 psi

This is the first time Cup teams have run these two tire codes at Kansas, though they did run the left-side code at Charlotte Motor Speedway last season. Compared to what was run at Kansas in 2016, this left-side tire code (D-4698) features a compound change for more grip. Like at Kansas last year, this year’s right-side tire code (D-4720) is one of Goodyear’s multi-zone tread tires, with two different compounds on the same tire — one on the inboard two inches (Endurance
Zone) for more heat and wear resistance, and one on the outboard 10 inches (Traction Zone) for more grip.

This right-side has the same tread compounds as the 2016 Kansas tire, but features a construction change to bring it into line with what is run at Texas Motor Speedway.

Camping World Truck Series

Teams will be allowed six sets of tires for the entire race weekend.

Tire Codes: Left-side — D-4670; Right-side — D-4718

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

Minimum Recommended Inflation: Left Front — 22 psi; Left Rear — 20 psi; Right Front — 54 psi; Right Rear — 50 psi

This is the first time Truck teams have run this right-side tire code (D-4718), though they did run this left-side code (D-4670) at Kansas last May. The new right-side tire features the same tread compound as the 2016 Kansas tire, with a construction change to bring it into line with what is run on the Cup cars. The right-side tire will also be run by teams in all three NASCAR national series at Texas later this year.

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

NASCAR: Will Jimmie Johnson, Kyle Busch advance in playoffs?

Leave a comment

The last two drivers to win NASCAR Cup titles are in precarious positions ahead of the Round of 12 elimination race at Kansas Speedway.

Kyle Busch, the 2015 champion, is outside the top eight in ninth. He sits seven points behind defending champion Jimmie Johnson.

NASCAR America analysts Kyle Petty and Parker Kligerman debated who they think had the best chance to advance to the Third round after Sunday.

Petty put his money behind Busch, who has finished in the top five in each of his last five starts at the 1.5-mile track.

“He’s one of the big three: Truex, Kyle Busch and Kyle Larson,” Petty said. “I don’t see where these (last) two races (Charlotte, Talladega) have changed anything. The one thing Kyle Busch brings into Kansas City … he brings speed. These guys have had speed all year-long.”

Johnson on the other hand has produced only four top fives all season and just one since he won at Dover in June.

But Kligerman explained why he thinks the seven-time champion will prevail on Sunday.

“Jimmie Johnson knows how to pass and that is what has become evident throughout this season,” Kligerman said. “No, they have not had the fastest cars at Hendrick Motorsports. No, they have not qualified well. They’ve actually been sort of abysmal at qualifying of late.

“… He has three wins this year. Two of those he started at the back.”

Daniel Hemric gets unexpected introduction to Cup car at Charlotte road course test (video)

Leave a comment

Being a native of Kannapolis, North Carolina, a lot of Daniel Hemric‘s racing firsts are connected to Charlotte Motor Speedway.

The 26-year-old Xfinity Series driver got another one this week when an unexpected call shortened a vacation to Mexico and put him in a Cup car for the first time.

Hemric, who drives Richard Childress Racing’s No. 21 Chevrolet in his rookie season, was visiting the country as part of a birthday vacation for his wife, Kenzie.

“As soon as the wheels touched down I got a call from some guys a RCR asking ‘Hey, would you mind driving a Cup car Tuesday at a test?'” Hemric said Wednesday.

“Do I need to fly home right now or what?” Hemric responded.

Come Tuesday morning, Hemric was sitting in the cockpit of Ryan Newman‘s No. 31 Chevrolet as one of four drivers taking part in the first Goodyear tire test on the Charlotte Motor Speedway road course, a 2.42-mile, 18-turn circuit made up of most of the original 1.5-mile track and the infield road course.

The two-day test could give Hemric a step up on his Xfinity competition as the series also will run on the road course next year.

“The first two or three runs was about getting me acclimated (to the car) but since then I think we’ve done a good job of communicating with Goodyear and trying to figure what we need to be able to make sure fans will be able to see racing and side-by-side racing and a lot of action, which I think you’re going to see.”

Added Hemric: “These Cup cars get up to speed so quick compared to the Xfinity car, with such low downforce and high horsepower. It’s been fun to figure out how to get that laid down here around the roval.”

Luckily, Kurt Busch, Martin Truex Jr. and Jamie McMurray were all experiencing the road course for the first time.

“Obviously, being my first time in (a Cup car), you’re trying to be aware of what you’re doing yourself,” Hemric said. “But to be able to lean on those guys, have the same thoughts as them, really collaborate with NASCAR and the race track to figure out where we should place those chicanes and all that stuff. I feel like we’ve made a lot of progress working as a group.”

SS Green Light Racing announced Thursday Spencer Boyd will compete full-time for it next season in the Xfinity Series.

Boyd will drive the No. 76 Chevrolet sponsored by Grunt Style, a veteran-owned lifestyle brand.

Boyd, 22, has made four starts for the team this year in the No. 07 Chevrolet, which has primarily been driven by Ray Black Jr.

“This is the day I’ve been waiting for my whole life,” Boyd said in a press release.  “I’ve been racing something since I was 5 years old with the dream of making racing my career. Grunt Style has made my dreams come true.”

A native of St. Louis, Missouri, Boyd has 12 starts between the Camping World Truck Series and Xfinity Series. In six Xfinity starts, including the four this year, his best result is 27th at New Hampshire.

Jason Miller will serve as the crew chief on the car that is owned by Bobby Dotter. Dotter has fielded cars in 116 races in the Xfinity Series since 1995 and 305 Truck Series entries since 2004.

“(Spencer) is one of the hardest working drivers I’ve seen,” Dotter said in the press release. “He is at the shop everyday helping with the cars and making the guys laugh.  Our organization is better because the team believes it when he says this is a team sport.  We are looking forward to a great 2018 season.”
