Yokohama's Eco-Friendly Tyre


Japan-based Yokohama Rubber Co., Ltd. (YRC) has created a new eco-friendly tyre made from citrus oil.

The manufacturing process for the new E-Spec passenger car tyre combines citrus oil with natural rubber to form a new compound called 'Super Nanopower Rubber’ (say that three times quickly). It features citrus instead of petroleum and apparently cuts petroleum use in tyre manufacturing by 80 percent. The company claims the citrus oil makes 'better tires for consumers and the environment', and is part of YRC’s global EcoMotion environmental program to create more environmentally-friendly products.

According to Jim MacMaster, executive vice president, Business Division, of Yokohama Tire Corporation, YRC’s U.S. subsidiary, the fuel-saving E-Spec tyre features an air permeation suppression film. “This new polymer inner lining is designed to reduce air from seeping out from the tyre, which helps maintain appropriate inflation levels. Underinflated tyres consume more power, thus using more fuel.

“The E-Spec is also a lot lighter and conserves gasoline by reducing rolling resistance by 18 per cent. Low rolling resistance tyres improve fuel efficiency by minimizing the energy wasted (as heat) as the tyre rolls down the road.”

The E-Spec tyre featuring the SNR compound will be available in Japan later in the year, but MacMaster said no date has been determined for release in the US market.
