Cooper Tire & Rubber Co.’s new Roadmaster RM332 WB heavy-duty wide base tire in sizes 425/65R22.5 in load range L and 385/65R22.5 in load range L is designed for the steer axle in mixed service applications.
A rib-type tread pattern withstands the rigors of heavy haul driving, on- or off-road, while also providing long tread life and even wear, according to the company. The cut-and-chip resistant tread compound is formulated for mixed service applications.
The RM332 WB is designed to preserve the casing for retreading. The tire’s features include a protective curb bar on both sidewalls, stone protector ledges in all four circumferential grooves to help resist stone penetrations, and four heavy-duty, full-width steel belts to promote durability in heavy haul fleets.
