Goodyear Fast Facts — Chicago Street Course
This weekend’s Chicago Street Race marks the third road course on the NASCAR Cup Series schedule, with the field racing on the same Goodyear Racing Eagle tires used earlier this season at Circuit of the Americas (COTA) and Autodromo Hermanos Rodriguez (Mexico City). The tire, which was introduced at COTA, has a different compound and construction than what was used in Chicago last year.
“We’ve been very encouraged by what we saw from the Cup Series road course tire at COTA and Mexico City,” said Stu Grant, Goodyear general manager of global race tires. “Our goal was to create a road course tire with more wear and fall-off, and we’ve seen just that.”
Both series will have wet weather tires available in the case of inclement weather. In addition to the tread difference, these tires feature white “Goodyear Eagle” lettering on the sidewalls instead of the traditional yellow.
