Storyline – High-speed road course requires a high-speed tire: As NASCAR was getting ready for its first races on the road course at Daytona International Speedway, Goodyear was already looking to its own racing history to come up with a tire set-up. With many years of history on this course in IMSA, Grand Am and Trans Am, Goodyear had a bit of a head start on what to bring to the track. This is a fast course that incorporates much of the two-and-a-half-mile oval that has been a staple of the NASCAR Cup schedule since 1959. With speeds expected to be close to what the Cup cars run at Watkins Glen International – as compared to a slower, more technical course like Sonoma Raceway – the Watkins Glen tire was determined to be the best fit.

"Our history in other series at Daytona, plus our extensive experience with these cars on the oval, helped us come up with our decision," said Greg Stucker, Goodyear’s director of racing. "We are very familiar with the requirements of running the banking as a part of this road course, and that helped us with choosing a tire with the correct compounds. While we were not able to run a test with the Cup cars on the course, we did confirm our recommendation using the simulation data that NASCAR and the OEM’s generated. The Watkins Glen tire is a good choice for this high speed course from a technical standpoint, and it is also a known quantity for the teams."

Notes – All three series on Watkins Glen tire for Daytona road course debut: Teams in all three NASCAR series in action on the Daytona road course will run the same tire . . . like at other NASCAR road courses, teams will run the same Goodyear tire code on all four corners of the car . . . this code is the same one Cup and Xfinity cars ran at Watkins Glen last season . . . as on all NASCAR road courses, teams will not run inner liners in their tires on the Daytona road course.

Wet Weather Tires – White-lettered tires on hand: Goodyear will bring its wet weather radials for use by teams in all NASCAR series on the Daytona road course, should NASCAR decide that conditions warrant . . . teams in each series are allowed up to two sets of "wets" for their race . . . this tire was last run by NASCAR Xfinity Series teams at Road America last week . . . in addition to the obvious difference of a tread pattern versus Goodyear’s dry weather "slick" tires, the "Goodyear" and "Eagle" lettering on the sidewalls of the wet weather tires is white, not the standard yellow.
