FULLERTON, CA (Oct. 26, 2009) – Yokohama Tire Corporation’s eco-friendly dB Super E-spec™ tire, which is composed of 80 percent non-petroleum-based products, accumulated high test scores when compared to low rolling resistance competitors during Tire Rack’s recent Real World Road Ride.
“The Tire Rack test shows that the dB Super E-spec, which introduces new technology in tire materials & design, is noticeably better on all-around performance,” said Mark Chung, YTC director, corporate strategy & planning. “Compared to standard tires on a Prius, both the fuel efficiency & h&ling are improved, & compared with other conventional tires that offer enhanced fuel efficiency, the dB Super E-Spec excels in driving performance. As the only manufacturer reducing petroleum by infusing orange oil into the tires, the dB Super E-spec st&s above the competition.”
Seven 185/65R15-sized OE & aftermarket tires with low rolling resistance capabilities were compared during more than 550 miles of real-world driving in a Toyota Prius on expressways, state highways & public roads. The dB Super E-spec was top-rated in h&ling, according to Tire Rack, which stated: “…the personality & drivability of the Prius can be affected by what tire is installed. The firm ride of the dB Super E-spec paid back with a quick, athletic feel as it responded crisply to driver inputs.”
The eco-focused dB Super E-spec mixes sustainable orange oil & natural rubber making it 80 percent petroleum free. The tire, which hit the U.S. market in July & is available in four sizes, also improves fuel efficiency via a 20-percent reduction in rolling resistance & by its proprietary Advanced Inner Liner, which is lighter than conventional butyl liner. The Advanced Inner Liner minimizes tire weight & reduces air loss to help the tire stay properly inflated.
“We feel the Tire Rack test shows that the dB Super E-spec is the perfect tire for consumers seeking a blend of excellent traction & h&ling in addition to environmental benefits,” said Chung. “It reinforces our feeling that Yokohama is the only brand introducing tomorrow’s technology today.”
