Both the Cup and Xfinity Series will race on the same tire compound this weekend at Chicagoland Speedway.

The right-side tires in the Cup and Xfinity Series will be the same as the one run in 2017, but the left-side will be different. The construction of the tire has been designed to align it with what is run at other speedways. The left-side tire features two compounds across the thread. The inside two inches of the tire has been designed for heat resistance, while the outside 10 inches are designed to maximize grip. The Cup and Xfinity series ran this same left-side tire at Auto Club Speedway in March.

“I think we made a nice grip improvement at Chicagoland last season, and we return with the same multi-zone tread right-side tire this season,” said Greg Stucker, Goodyear’s director of racing, in a press release. “The track surface at Chicagoland has really weathered over the past several seasons and as a result we see a good amount of wear and fall-off. That, with the tire combination we bring, helps promote some good racing with tire management coming into play with both ‘comers’ and ‘goers’ throughout the field each run.”

Here’s the tire info for Cup and Xfinity.
