Yokohama Tire Corp.’s RL42 and RB42 OTR tires are designed for dump trucks but have two different applications: The RL42 is for hard-packed surfaces and jobsites where longer hauls are needed, while the RB42 is made for soft and/or loose surfaces such as mud, sand, gravel and rocks. Both tires feature an extra-durable casing and a deep flush tread, and both also have steel cord belts to guard against tread punctures and buttress side protection that helps protect the sidewalls from snags and cuts.
The RL42, which comes in sizes 1800R33 and 2400R35, features circumferential grooves designed to dissipate heat to run cooler, enabling long-haul capabilities at jobsites; a directional tread pattern that helps improve self-cleaning for increased traction; and deep, wide grooves that help expel mud and dirt for better traction. The RB42 comes in sizes 1800R33 and 2400R35 and features a zig-zag groove pattern that helps provide better traction on muddy and rocky surfaces, while large center blocks help increase resistance to cuts and enhance overall wear.
