NASCAR Cup Series teams will pair a new left-side Goodyear Racing Eagle tire with a familiar right-side tire at Martinsville Speedway this weekend.
The new left-side tire, which is designed for more fall-off than its predecessor, will make its race debut at Martinsville having been tested earlier this year at New Hampshire Motor Speedway. The right-side tire has been used five times this year, including the spring race at Martinsville and most recently at New Hampshire in September.
