Cooper Tire & Rubber’s Roadmaster RM332 WB is a wide-base steer tire designed for mixed service applications.
The RM332 is now available in size 385/65R22.5 in load range L, in addition to size 425/65R22.5 in load range L. The tire has a 23/32nds tread depth for extended tread life in severe, high scrub applications and a cut-and-chip-resistant compound designed for the performance requirements of mixed-service applications.
The tire has a rib-type tread pattern to withstand different applications such as heavy-haul, on- and off-road, while providing long tread life and even wear. The RM332 WB tire includes a protective curb bar on both sidewalls and stone protector ledges in four circumferential grooves to resist stone penetrations.
These features help preserve the casing for retreading and with four heavy-duty, full-width steel belts, the tire promotes durability in heavy-haul applications.
