Goodyear tire info for Sprint Cup, Xfinity at Charlotte

Leave a comment

Sprint Cup and Xfinity Series teams will be competing on different tire setups this weekend at Charlotte Motor Speedway.

Sprint Cup will be using the same tires they had for the Coke 600 and the All-Star Race back May.

Teams will be allowed five sets of tires for practice and qualifying and 10 sets for the Bank of America 500.

Sprint Cup tire info

Tire Codes: Left-side — D-4698; Right-side — D-4700

Tire Circumference: Left-side — 87.44 in. (2,221 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

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

Xfinity tire info

Xfinity teams will be allowed eight sets of tires for the entire race weekend.

This is the same tire combination the series used in Charlotte in May.

Tire Codes: Left-side — D-4688; Right-side — D-4694

Tire Circumference: Left side — 87.56 in. (2,224 mm); Right side — 88.39 in. (2,245 mm)

Minimum Recommended Inflation: Left Front — 26 psi; Left Rear — 26 psi; Right Front — 54 psi; Right Rear — 50 psi

This right-side tire code employs Goodyear’s multi-zone tread technology, which combines two distinct tread compounds on the same tire — the outboard 10 inches of the tread (Traction Zone) features a compound that is designed for grip, while the inboard two inches of the tread (Endurance Zone) is toughened to enhance durability on the part of the tire that sees the most heat and takes the most abuse. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Denny Hamlin hopes teams don’t shoot selves in feet with pit guns

Leave a comment

Denny Hamlin is the hottest driver on the Cup circuit. He has two wins – including Saturday night at Bristol – as well as two runner-ups, and a third- and fifth-place finish in the last six races. He’s also moved up to third in the rankings in that string.

But Hamlin isn’t taking anything to chance, particularly some of the smallest details – such as loose lug nuts and wheels.

Hamlin appeared Monday on SiriusXM NASCAR Radio’s “On-Track” show and was asked about how not only his team, but also other Cup teams, can overcome the loose lug nuts and wheels issues.

Hamlin said a significant part of the problem – particularly at a place like Bristol Motor Speedway – is pit guns, which are allocated and issued in a pre-race lottery by NASCAR, rather than have teams use their own guns.

Hamlin does not like that system and explained why:

“(Bristol) puts probably some of the biggest loads we have on our tires. Truth be told, over the last two years since we’ve had these guns issued to us, they’re not capable of getting all the wheels tight, they really aren’t.

“It’s a lottery whether you get a gun that’s good enough to get ‘em tight. Through JGR, Stewart-Haas and other teams that have documented it, in the spring race there were over 20 loose wheels. This is not just a team thing. It’s just that the equipment is not quite up to par as far as what it’s capable of.

“We keep track of all the guns and how good they are and how bad they are. It’s a lottery system of whether you’re going to get (a good or bad one). It doesn’t matter how fast you go, you can hold the gun on there and it’s just not going to get the torque quite tight enough.”

Hamlin experienced a loose wheel that forced him to pit under green on Lap 186 of Saturday night’s race at Bristol, leaving him two laps behind the leaders. Hamlin had another loose wheel on Lap 374 and pitted while running 10th.

Thus far this season, in addition to several loose wheels in races, Hamlin’s team has also been penalized four times for loose lug nuts after races: Fontana, Bristol spring race, Chicagoland and the July race at Pocono.

This isn’t the first time Hamlin has publicly complained about pit guns and loose lug nuts and wheels.

NBC Sports has reached out to NASCAR for comment.

Check out what Hamlin said about that after Saturday night’s race in the video above (Hamlin talks about this issue starting around the 6:00 mark).

Dale Earnhardt Jr. thanks all who have ‘lifted us up’ since plane crash

Leave a comment

Dale Earnhardt Jr. issued his first public comments Monday since he and his family survived a plane crash last Thursday afternoon at Elizabethton (Tennessee) Municipal Airport.

Earnhardt offered thanks to “everyone who has lifted us up with phone calls, messages and prayer since last Thursday. We are truly blessed that all on board escaped with no serious injuries, including our daughter, our two pilots and our dog Gus.”

Earnhardt also thanked the pilots, emergency personnel, law enforcement and hospital staff.

He stated that wife “Amy and I continue to be very appreciative of the privacy extended to us to process everything. It has been important to do that together and on our own time.”

Earnhardt stated that because of the ongoing investigation “we will not be speculating or discussing the cause of the accident.”

A preliminary report from the National Transportation Safety Board is expected this week. Ralph Hicks, a senior investigator for the NTSB said in a briefing last Friday that “the airplane basically bounced at least twice before coming down hard on the right wing landing gear. You can actually see the right wing landing gear collapsing on the video (from nearby buildings). The airplane continued down the runway, off to the end, through a fence and came to a stop … on highway 91.”

Both pilots have been interviewed and Hicks stated that what they said was “very consistent” with what the video showed. Hicks also said investigators had talked to the Earnhardt family.
