Yokohama Tire Corp. said its new OTR tires – the RL42 and RB42 – are designed for dump trucks but have two different applications. According to Gary Nash, Yokohama director of OTR Sales, the RL42 is for hard-packed surfaces and job sites where longer hauls are needed, while the RB42 is made for soft and/or loose surfaces such as mud, sand, gravel and rocks.
“The unique tread and sidewall designs help create specialized tires for specific applications,” said Nash. “Yokohama is the only OTR manufacturer that builds tires to handle specific jobs.”
The RL42, which comes in sizes 1800R33 and 2400R35, features circumferential grooves that dissipate heat to run cooler, a directional tread pattern that improves self-cleaning for increased traction and deep, wide grooves that help expel mud and dirt for better traction, according to the company.
The RB42 comes in sizes 1800R33 and 2400R35 and features a zig-zag groove pattern that provides better traction on muddy and rocky surfaces, as well as large center blocks that increase resistance to cuts and enhance overall wear, the tiremaker said.
Nash said both tires feature an extra-durable casing and a deep flush tread. The tires also have steel cord belts to guard against tread punctures and buttress side protection that protects the sidewalls from snags and cuts.
