For over 90 years, Yokohama has been a world leader in the development of outstanding tire designs and technology, giving drivers better control on the road. Since its establishment in 1917, we have devoted ourselves to advancing the leading edge of the industry. We were the first Japanese tire manufacturer to be granted ISO9001 certification in recognition of a quality-assurance model-company in design, development, manufacture installation, and related services.  Yokohama also takes its responsibilities to the environment very seriously. Among our many ongoing initiatives, we have eliminated the use of CFCs and trichloroethane in the manufacturing process, and have switched from heavy oil to natural gas to reduce CO2 emissions and save energy.  Driven by the needs of people, Yokohama continues to respond with environmentally-compatible solutions engineered to outperform, whatever the performance need.
