Yokohama introduces lightweight, fuel-Efficient tyre; the BluEarth-air EF21

The Yokohama Rubber Company Limited has announced the development of the BluEarth-air EF21, a conceptual tyre based on the most advanced technologies and the latest design technique for reducing tyres’ weight and environmental impact. Developed to commemorate the Company’s 100th anniversary, the new tyre will be marketed in Japan on a limited basis this year in one developmental size, 205/55R16 91V.

In order to create a more environmentally friendly tyre, Yokohama Rubber has employed its latest design technique to achieve a lighter tyre that conserves resources by using less material and improves fuel efficiency by contributing to lighter overall vehicle weight. In addition to being light, the BluEarth-air EF21 has achieved a thin yet highly rigid structure and a weight reduction of about 25% in the tyre’s mass, the company said.

“The tyre also achieves wet and fuel-efficient performance from the use of a newly developed special compound and Yokohama Rubber’s state-of-the-art rubber mixing technology, Advanced Reaction Technology in Mixing. Besides, 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 tyre labeling system,” a statement from the company said.

The BluEarth-air EF21 will be displayed at the Yokohama booth at the upcoming 45th Tokyo Motor Show 2017, to be held at the Tokyo Big Sight from October 25 to November 5.
