Goodyear tire notes for Kansas Speedway

Leave a comment

Both the Sprint Cup and Xfinity Series will compete at Kansas Speedway this weekend, but they will be running different tire setups.

Sprint Cup teams will run the same tire combination they did at Kansas earlier this season. However, it will be the first time the Xfinity Series runs their tire setup at Kansas.

Sprint Cup tire info: 

Set limits: Sprint Cup – five sets for practice and qualifying and 10 sets for the race

Tire Codes: Left-side — D-4656; Right-side — D-4662

Tire Circumference: Left-side — 87.56 in. (2,224 mm); Right-side — 88.35 in. (2,244 mm)

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

This is the same combination of left and right-side tires that Sprint Cup teams ran at Kansas earlier this season. Kansas is the only track at which either of these two tire codes will be run by Sprint Cup teams in 2016.

This right-side tire code (D-4662) 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 that area of the tire which 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 Kansas. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Xfinity tire info: 

Set limits: Xfinity – seven sets for the event

Tire Codes: Left-side — D-4670; Right-side — D-4672

Tire Circumference: Left-side — 87.60 in. (2,225 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 is the first time Xfinity Series teams have run this tire setup at Kansas, though they did run this left-side tire code (D-4670) at Michigan International Speedway in June and this right-side tire code (D-4672) at Las Vegas Motor Speedway in March. Both the left and right-side tires feature the same compound run at Kansas last year, though there is a construction change to Goodyear’s updated speedway construction on both sides.

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.

Drivers include Denny Hamlin, Kyle Busch, Paul Menard, David Ragan, Kurt Busch, Kyle Larson, Corey LaJoie and Chris Buescher.

Buescher’s team also loses pit selection for Sunday’s race because it failed inspection three times.

Larson and LaJoie’s loss of practice time comes after neither qualified Thuraday because their cars didn’t clear inspection in time.
