Yokohama Tire Corp. announced it will implement a price increase of up to 10 percent on all of its off-the-road tires in the United States, effective May 1. There will be in-line adjustments, as well, which will be announced at a later date.

Gary Nash, Yokohama vice president, OTR Sales, said the price increase was not caused by the recent earthquake in Japan. “It’s from the escalating costs of raw materials, such as natural rubber,” he said. Additional factors necessitating the increase, according to Nash, are the rising costs in transportation and manufacturing. “We do our best to integrate our operational efficiencies, technology and environmental procedures to produce the best OTR tires at competitive prices. The increasing costs, unfortunately, must be reflected in our product pricing.”

Yokohama Tire Corp. is the North American manufacturing and marketing arm of Tokyo-based The Yokohama Rubber Co., a global manufacturing and sales company of premium tires since 1917. The company’s complete product line includes the dB Super E-spec — the world’s first tire to use orange oil to reduce petroleum — as well as tires for high-performance, light truck, passenger car, commercial truck and bus, and off-the-road mining and construction applications.
