Originally developed by its racing engineers, Yokohama Tire Corp. has introduced a passenger tire which is 80 percent petroleum-free, offering a 20 percent lower rolling resistance and lower weight. Using orange peels as its main ingredient, the dB Super E-spec passenger tire is less prone to lose pressure and will increase fuel economy.

Yokohama Vice President of Sales Dan King claims that the tire, by maintaining air pressure and reducing resistance will substantially increase fuel efficiency without any reduction in performance. A special proprietary substance, called Super Nano-Power Rubber is the agent which reduces rolling resistance and improves performance. The tire will originally be sold in four sizes which are consistent with those on the Toyota Prius Hybrid and the Honda Accord Hybrid.

As a winner of one of Popular Mechanics Editor's Choice Awards at the SEMA Show in Las Vegas in 2008, the tire has received accolades for its use of sustainable, non-petroleum materials with high recyclability and its ability to increase fuel efficiency. No other tire has the combined benefit of improved performance and eco-friendly construction.
