Cooper Expands Roadmaster Line With Wide Base Tire

April 27, 2016

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

The Roadmaster RM332 WB has a rib-type tread pattern that Cooper says is specially designed to withstand the rigors of heavy haul driving, on- or off-road, while also providing long tread life and even wear.

The cut and chip resistant tread compound was formulated to meet the diverse performance requirements of mixed service applications. Additionally, the RM332 WB is designed to preserve the casing for retreading, including 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.

“Mixed service applications are highly demanding and this new tire stands up extremely well to a wide variety of uses,” says Gary Schroeder, Cooper’s director of commercial vehicle and global original equipment sales. “Our Roadmaster tires provide long miles and are backed by a strong warranty. These advantages, combined with attractive pricing, make Roadmaster a great tire for customers looking to reduce cost-per-mile."
