Cooper’s Roadmaster RM351 HD tire is engineered for mixed-service applications and is designed for both on- and off-road driving. A deep 32/32nds tread depth helps provide more miles to removal, and tie bars between the outside lug and the shoulder, along with shoulder grooves that are linked and interlocked, ward off tire squirm and irregular wear. The robust casing is a four-belt steel design, and the thick sidewall has a curb bar protector to shield the casing from cuts and scrubbing. Five lugs have an open pattern to minimize stone holding while enhancing traction, while stone ejector ledges, coupled with angled grooves, help prevent stone drilling. The tire comes in two sizes: 11R22.5 and 11R24.5, in load range H.
