Storyline – As temperatures fall in late fall, tire wear becomes important: With temperatures expected to be in the 50s this coming weekend, introducing tire wear on Martinsville Speedway’s concrete corners will become a critical factor in this weekend’s NASCAR races. Goodyear has designed its tread compounds for the flat, half-mile track to specifically lay rubber in colder temperatures. Laying rubber on the track surface allows for a second racing groove to develop, thus making for more side-by-side racing and passing opportunities around the tight track.
“The last time we raced at Martinsville, it was June and both ambient and track temperatures were not a concern,” said Greg Stucker, Goodyear’s director of racing. “We’ve had a lot of cold weather races at this track over the past several years, so we did some work on developing tread compounds that would lay rubber in the concrete corners in those conditions. The results have been good, as we’ve seen the surface turn from white to black in the corners, giving drivers the ability to move up the track to find grip. The resulting second lane has helped produce some great racing along the way.”
Notes – Same tire set-up for Cup cars; first outing for Xfinity, Trucks: Teams in all three NASCAR national series will run the same tire set-up at Martinsville this week . . . this is the same combination of left-and right-side tires that Cup teams ran at this track in June . . . for Xfinity, this is their first race at Martinsville since 2006 . . . for the Trucks, this is the first time they have run either of these two tire codes . . . compared to what the Trucks ran at Martinsville last November, this tire set-up features construction updates on both sides of the car and compound changes on both sides that will give the cars more grip and introduce more tire wear . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Martinsville.
