NASCAR Cup and Truck teams continue their respective playoffs this weekend at Martinsville Speedway.
The Cup Series begins its Round of 8, while the Gander Outdoors Truck Series will contest its middle race of the Round of 6.
Cup and Truck teams will run the same tire setup at Martinsville, the same tires both series have run at the .526-mile bullring since 2017.
“It’s getting later in the fall and we are likely to have cloudy conditions and temperatures in the 60-degree range at Martinsville this week, so track temps will be low, making it more difficult for the track to take rubber,” said Greg Stucker, Goodyear’s director of racing. “Because of the time of year we run at Martinsville, we’ve worked hard over the past several years to come up with a tread compound that will lay rubber in the concrete corners, even in cool temperatures.
“Generally, Martinsville has produced some of the best racing on the circuit and that only seems to have been enhanced by the track consistently taking rubber and having multiple racing lines. We continue to work on keeping up with Martinsville and making adjustments where needed, holding a test there this past summer and looking ahead to 2020 when we will have a full fledged night race at the track.”
According to wunderground.com, the forecast calls for a temperature of 58 degrees with a 40 percent chance of rain at the scheduled 1:30 p.m. ET start time for Saturday’s Truck race, and a temperature of 66 degrees with a 19 percent chance of green flag at the 3 p.m. ET scheduled start time for Sunday’s Cup race.
