Roadmaster RM351 HD tire is engineered for mixed-service applications such as on a mixer or dump truck, and is designed for both on- and off-road driving.
The on- or off-road tire comes in two sizes: 11R22.5 and 11R24.5, in load range H. The tire is a full inch wider than its predecessor, the RM300 HH, with a 20 percent larger footprint. Coupled with its 32/32nds tread depth, it provides up to 25 percent more miles to removal, depending upon the application, the company says.
Tie bars between the outside lug and the shoulder, along with shoulder grooves that are linked and interlocked, help ward off tire squirm and irregular wear. The sidewall is extra thick with a curb bar protector to help protect the casing from cuts and scrubbing, and the casing itself has a four-belt steel design construction.
