After two road course races, NASCAR heads to Dover Motor Speedway and its challenging 1-mile concrete oval. Moving from an April date to July is expected to bring higher temperatures to Delaware as drivers battle out the penultimate round of the In-Season Challenge.
A new Goodyear Racing Eagle tire setup designed specifically for the Monster Mile’s ever-changing track surface awaits NASCAR Cup Series teams. The new tire has been designed to withstand the high speeds and high loads associated with racing at Dover, and won’t be used at any other track this season.
“Laying rubber down on the concrete surface is a key factor in the design of our tread compounds for Dover,” said Rick Heinrich, Goodyear NASCAR product manager. “While the track turns black as cars lay rubber down during green flag racing, the hot tires then pick up this same rubber when the track cools under cautions. Dover presents a unique opportunity to engineer a tire to help in laying down rubber on a particularly smooth surface, and we’ve designed the product to do just that.”
In contrast to the new Cup Series setup, NASCAR Xfinity Series teams will use familiar tires at Dover. This is the fourth consecutive race at Dover using this Xfinity Series tire setup, and both tires have already been used this season: the left-side tire five times so far and most recently at Pocono, and the right-side tire at Nashville. Unlike the Cup Series, Xfinity Series teams use inner liners on ovals 1-mile and longer, including Dover.
