Yokohama’s eco-friendly dB Super E-spec tire, comprised of 80 percent non-petroleum-based products and infused with orange oil, 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 and design, is noticeably better on all-around performance,” says Mark Chung, Yokohama’s director of corporate strategy and planning.

“Compared to standard tires on a Prius, both the fuel efficiency and handling are improved, and compared with other conventional tires that offer enhanced fuel efficiency, the dB Super E-Spec excels in driving performance,” he reports. “As the only manufacturer reducing petroleum by infusing orange oil into the tires, the dB Super E-spec stands above the competition.”

Seven 185/65R15-sized original equipment and 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 and public roads.

The Yokohama entry was top-rated in handling, according to Tire Rack, which stated: “…the personality and 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 tire, which hit the U.S. market in July and is available in four sizes, improves fuel efficiency via a 20 percent reduction in rolling resistance and by its proprietary Advanced Inner Liner, which is lighter than a conventional butyl liner, Chung says. The liner minimizes tire weight and reduces air loss to help the tire stay properly inflated, he explains.

“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 and handling in addition to environmental benefits,” Chung notes. “It reinforces our feeling that Yokohama is the only brand introducing tomorrow’s technology today.”
