Cooper’s Roadmaster RM332 WB heavy-duty wide base tire, available in size 425/65R22.5, is designed for the steer axle in mixed-service applications. The RM332 WB’s rib-type tread pattern and cut- and chip-resistant tread compound are designed for on- or off-road heavy-haul driving and to provide long tread life and even wear. The tire is engineered to preserve the casing for retreading and includes a protective curb bar on both sidewalls, stone protector ledges in all four circumferential grooves that help resist stone penetration, and four heavy-duty full-width steel belts to promote durability.
