TOKYO—The sanctioning body for Japan's Super Formula racing series—the nation's top formula-car racing competition—has extended its race tire supply agreement with Yokohama Rubber Co. Ltd. (YRC) through 2023.
At the same time, Yokohama—which has been Super Formula's designated race tire supplier since 2016—said it plans to develop racing tires made from sustainable materials, such as silica produced from rice husks, oil from oil palm fruit nuts and orange peels as well as rubber recycled from scrap tires.
Yokohama stressed that its plans to use sustainable materials will not affect racing car performance negatively.
The tire maker's plans are tied to a Super Formula Next50 initiative announced October 2021 by Japan Race Promotion Inc., the entity that runs the Super Formula series. The SF Next50 project is being promoted with the cooperation of various companies that share the common goal of creating a sustainable motorsports industry by responding to changes in the environment surrounding the automobile and motorsports industries.
