TOKYO (June 28, 2013) — Yokohama Rubber Co. Ltd. has released the RB42, a large-size radial tire for rigid dump trucks in the construction and mining field.
Yokohama said the tire has a TRA code— a classification of tire use and tread by the U.S. Tire and Rim Association Inc.—of E-4 and a star rating for tire strength of " **." The RB42 is available in 27.00R49 size model.
Features include regular specifications for ordinary off-the-road surfaces, the tire manufacturer said, and "cut protected"—with cut resistance for a wide range of surfaces, from soft or loose surfaces such as mud or sand, to rough surfaces comprising gravel and rocks.
The Tokyo-based tire maker said the RB42 also has a new belt structure for large-size radial tires and a specialized mold profile, along with utilizing an exclusive tread compound, also newly developed for large-size radial tires. The result is improved wear resistance, cut resistance and durability, according to the company, along with a block tread pattern that balances wear resistance, traction and efficient mud ejection.
