Reports out of China state that Chinese authorities have audited and approved research by Linglong Tire into the "large-scare application" of graphene rubber composites in tires".
The research was conducted jointly by Beijing Tiancheng Linglong Tire, a wholly-owned subsidiary of Linglong Tire, and Beijing University of Chemical Technology. An audit was conducted by Beijing Municipal Science & Technology Commission along with other Chinese technology institutes.
The graphene tires, Linglong said, showed promising results in several areas including fuel-efficiency, safety and anti-static, and energy-saving. More specifically, Linglong said a fuel-efficient grade of its graphene tire was close to a grade A rating under EU tire labeling regulations.
Linglong also linked the fuel-consumption improvements to a "micro-interface technology" developed by the research team.
In terms of wet-grip, the Chinese tire maker expects the product to achieve an A grade under EU labeling protocol.
The abrasion resistance and thermal conductivity of the tires have "varying degrees of improvement" over high-performance "green" tires on the market, added Linglong.
