Cup and Xfinity Series teams will head to Darlington Raceway this weekend with a new tire combination for the 1.366-mile track.

Each series will use the same tire combination. This is the first time teams have run this left-side tire code. The right-side tire was first raced in May at Charlotte Motor Speedway.

Compared to what teams ran last year, this left-side tire features a construction update to align it with what is run at other speedways, while the right-side tire has a compound change to give the cars more grip.

This tire setup came out of a Goodyear test at Darlington on June 5-6. Drivers who participated in that test were Matt Kenseth, Jamie McMurray, Paul Menard and Daniel Suarez.

Here’s the tire info for the weekend.
Set limits: Cup: Three sets for practice, One set for qualifying and 13 sets for the race; Xfinity: Seven sets for the event

Tire Circumference: Left-side -- 2,216 mm (87.24 in.); Right-side -- 2,251 mm (88.62 in.)
