Tire Rack Tests Yokohama’s Orange Oil Tyre in 'Real World Ride'

Yokohama Tire Corporation's (YTC) eco-friendly dB Super E-specT tyre, which is made of 80 per cent non-petrol products, scored well in a recent low rolling resistance test conducted by US retailer Tire Rack. "The Tire Rack test shows that the dB Super E-spec, which introduces new technology in tyre materials and design, is noticeably better on all-around performance," said Mark Chung, YTC director, corporate strategy and planning. "Compared to standard tyres on a Prius, both the fuel efficiency and handling are improved, and compared with other conventional tyres that offer enhanced fuel efficiency, the dB Super E-Spec excels in driving performance.”

Seven 185/65R15-sized OE and aftermarket tyres with low rolling resistance capabilities were compared during more than 550 miles of driving a Toyota Prius on expressways, state highways and public roads.  The dB Super E-spec was top-rated in handling, according to Tire Rack: “the personality and drivability of the Prius can be affected by what tyre 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, which contains orange oil and natural rubber in place of petroleum based products, hit the US market in July and is available in four sizes. The tyre is said to improve fuel efficiency via a 20-per cent reduction in rolling resistance and an advanced inner liner. The fact that the latter is lighter than standard inner liners and is reportedly better at reducing air loss is said to help the tyre stay properly inflated.
