FULLERTON, Calif. — Record increases in the cost of raw materials and energy have caused Yokohama Tire Corporation to increase prices on its large and extra large bias/radial off-the-road (OTR) tires up to 4%, and on its medium-truck and light truck commercial tires by up to 6%, effective Sept. 1.

The announcement was made by Jim MacMaster, executive vice-president of Yokohama’s business division, who added there will be in-line adjustments, as well, which will be announced at a later date. Consumer tires will not be affected by the increase.

“We are doing our best to contain costs – through efficient operations and by using the latest manufacturing technologies,” said MacMaster. “However, raw materials, energy and transportation costs continue to soar and our pricing, unfortunately, must reflect these record-high costs. We remain committed as always though, in bringing the best products to market with the most competitive prices.”
