The Cup and Xfinity Series go back this weekend to where it all began for NASCAR: Daytona International Speedway.
Here’s the Goodyear Tire info for this weekend’s racing action at the World Center of Racing:
Teams in the two series will run different tire set-ups, with Cup cars riding on rubber with two new tire codes compared to what was run earlier this year at the Daytona 500. Both the left- and right-side tires “feature construction updates to align this set-up with what is run at intermediate tracks,” Goodyear said in a press release.
The tire set-up stems from a Goodyear test at Daytona right after the 500 on February 18-19. Teams that participated in that test were Richard Childress Racing (Daniel Hemric), Chip Ganassi Racing (Kyle Larson) and Hendrick Motorsports (Alex Bowman).
“The goal was to incorporate the basic elements of the 2019 rules package into the aerodynamic configuration for the superspeedways of Daytona and Talladega, so they are no longer unique in that perspective,” Goodyear director of racingGreg Stucker said in a media release. “With that alignment established early in the test, we took the same approach to the tires.
“The result was a tire combination with the same constructions we run at the intermediate tracks, married with the tread compounds run at Daytona in February. Having such a great working relationship with NASCAR allows us to get a lot accomplished together at our tests that ultimately has a positive impact on what we all bring to the track and the quality of racing we put on for our fans.”
