The Yokohama Rubber Co. has released 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 U.S. Tire and Rim Association code of E-4 and a two-star rating for tire strength, according to Yokohama, which added the lineup features "Regular" specifications for ordinary off-the-road surfaces, and "Cut Protected" specs with excellent cut resistance. This makes the 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, the tiremaker added.
RB42 features a new belt structure for large-size radial tires and a specialized mold profile, as well as an exclusive tread compound that is newly developed for large-size radial tires.
“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,” the tiremaker said. “In this circumstance, Yokohama intends to expand its presence in the mineral resources development sector through this official release of the large-size RB42.”
