Yokohama Rubber to Launch European Sales of Ultra Lightweight and Fuel-Efficient “BluEarth-air EF21”

Tokyo – The Yokohama Rubber Co., Ltd., announced today that it will begin selling its “BluEarth-air EF21” in Europe on a limited-basis from this spring. The “BluEarth-air EF21” uses the most advanced technologies to achieve a new lightweight design that enhances its environmentally sound features. The tire will be available in only one size, 205/55R16 91V.

Seeking to create a more environmentally friendly tire, Yokohama Rubber has employed its latest design technique to achieve a lighter tire 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 tire’s mass. * The tire also achieves excellent 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. As a result, the “BluEarth-air EF21” has received the European tire-grading system’s highest “A” grades for both rolling resistance and wet grip performance.

BluEarth is a YOKOHAMA global tire brand based on the concept of being “environmental, human, and socially friendly”. The brand’s diverse lineup also includes the high-performance, fuel-efficient “BluEarth-A”; the fuel-efficient “BluEarth RV-02” for minivans and crossover SUVs; and the “BluEarth-Es ES32”, a fuel-efficient standard tire.

* Compared with the “ADVAN dB V551”, the YOKOHAMA tire considered to be the standard for tire mass.
