Wide-Base Tire

Cooper Tire & Rubber is adding to its Roadmaster line of commercial tires with the introduction of the new RM332 WB heavy-duty wide-base tire in size 425/65R22.5. It’s designed for the steer axle in mixed-service applications.

The Roadmaster RM332 WB has a specially designed rib-type tread pattern to withstand the rigors of heavy-haul driving, on or off road, while also providing long tread life and even wear, says Cooper. The cut-and-chip-resistant tread compound was specially formulated to meet the diverse performance requirements of mixed-service applications.

The RM332 WB is also designed to preserve the casing for retreading, using 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.

The new RM332 WB is backed by a Roadmaster warranty that offers two retreads within six years.
