Storyline – Robust construction and rubbering-in corners are keys to Martinsville: Martinsville Speedway presents a unique challenge when designing a tire set-up.  The track configuration calls for hard braking entering the tight corners and hard acceleration off to carry speed down the relatively long straightaways.  That combines with the fact that it is a combination track surface of asphalt straightaways and concrete corners.  Laying rubber on the concrete is the goal, and something Goodyear has worked hard on over the years, considering the uncertain weather demands when racing in Southern Virginia this early in the year.

“For our set-up at Martinsville, we have a challenge to address with both the construction of the tires and the tread compounds,” said Greg Stucker, Goodyear’s director of racing.  “As far as the construction, it has to be robust enough to handle the hard braking and acceleration on and off the corners, which have no banking to speak of to help.  What we try to do with the compounds is bring something that will wear and rubber-in the concrete corners in sometimes cool conditions.  Rubbering-in the lower groove creates a second lane on the track and gives drivers more opportunity to pass.  This Cup set-up is very similar to what teams ran in The Clash, including the same left-side tire.”

Notes – Cup teams to run Clash left-side tire at Martinsville: Having moved to an 18-inch bead diameter tire for 2022, NASCAR Cup teams will run a different tire set-up than those in the Xfinity and Truck Series at Martinsville this week . . . this is the same left-side tire Cup teams ran in The Clash at the Los Angeles Memorial Coliseum in February, but with a different right-side tire . . . in addition to the obvious construction changes to what Cup teams ran at Martinsville last season, this left-side tire features a compound change to give the cars more grip and help rubber-in the concrete corners . . . with this 18-inch tire, and its lower profile sidewall, NASCAR Cup cars will not run inner liners in any of their tires in 2022.
