Yokohama Rubber has announced the development of its “BluEarth-air EF21”, a conceptual tire designed to reduce tires’ weight and environmental impact.

The concept tire was developed to commemorate the company’s 100th anniversary, and will be marketed in Japan on a limited basis this year in one developmental size, 205/55R16 91V.

Yokohama Rubber has worked to create a lighter, more environmentally-friendly tire that requires less material to produce and improves fuel efficiency by contributing to lighter overall vehicle weight. In addition, the BluEarth-air EF21 has received a “AAA” grade for rolling resistance and an “a” grade for wet grip performance, the highest grades awarded under Japan’s tire labeling system.

The BluEarth-air EF21 will be introduced to the world at the Yokohama booth at the upcoming 45th Tokyo Motor Show 2017. The show will be held at the Tokyo Big Sight from October 25 to November 5, and will be open to the general public from October 28.

BluEarth is a Yokohama global tire brand based on the concept of “environmentally, human, and socially friendly.” Other tires in the BluEarth brand  includes: BluEarth-A, which combines excellent wet performance with high fuel efficiency; the BluEarth RV-02, a fuel-efficient tire for minivans and CUVs, and the BluEarth-Es, a fuel-efficient standard tire.
