OREANDA-NEWS. The Yokohama Rubber Co., Ltd., announced that it officially released in June a large-size radial tire for rigid dump trucks in the construction and mining field - a 27.00R49 size model of its "RB42." The tire has a TRA code of E-4 and a star rating for tire strength of " **." The lineup features "Regular" specifications for ordinary off-the-road surfaces, and "Cut Protected," with excellent cut resistance. Thus, tires suitable for a wide range of surfaces, from soft or loose surfaces such as mud or sand, to rough surfaces comprising gravel and rocks, are available.

For the "RB42," in addition to a new belt structure for large-size radial tires and a specialized mold profile, YOKOHAMA utilizes an exclusive tread compound, also newly developed for large-size radial tires. The result is excellent wear resistance, cut resistance and durability. As a tread pattern, a block tread pattern is employed, which balances wear resistance, traction and efficient mud ejection.

"Deploying High-Value-Added Products Globally" is part of YOKOHAMA’s growth strategy for tires in Phase III of its "Medium-Term Management Plan: Grand Design 100 (GD100)." Large-size radial tires for construction and mining vehicles are one such value-added product with which YOKOHAMA can highlight its performance superiority. The global production of mineral resources is intensifying and with it over the medium and long term is increasing demand for large- and ultra-large radial tires. In this circumstance, YOKOHAMA intends to expand its presence in the mineral resources development sector through this official release of the large-size "RB42."
