Developed to mark the company’s 100th anniversary, the new tire will be marketed in Japan on a limited basis this year in one developmental size, 205/55R16 91V, said a press announcement.
As well as using less material, the BluEarth-air EF21 features a thin yet highly rigid structure and a weight reduction of about 25% in the tire’s mass – compared with the ADVAN dB V551, the company’s standard for tire mass.
The new tire is also said to deliver “excellent” wet and fuel-efficient performance due to the use of a newly developed compound. This is processes using an advanced Yokohama rubber mixing technology, called ‘advanced reaction technology in mixing’.
According to Yokohama, the concept tire has received an ‘AAA’ grade for rolling resistance and an ‘A’ grade for wet grip performance, the highest ratings awarded under Japan’s tire labelling system.
The tire was introduced at the Tokyo Motor Show 2017, being staged 25 Oct to 5 Nov.
