Cooper adds wide-base steer tire

New steer tire designed for mixed service applications, specifically for heavy-haul driving, on- and off-road operation, while offering long tread life and more even wear.

Cooper Tire & Rubber Co. is adding a new size to its Roadmaster RM332 WB commercial tire line; 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 introduced in April.

The RM332 WB model wide-base steer tire designed for mixed service applications, the company said, offering 23/32nds of tread depth to provide extended tread life in severe, high scrub applications, along with a cut and chip resistant compound specially formulated to meet the diverse performance requirements of mixed service applications.

Cooper added that its new tire (seen at right) features a specially designed rib-type tread pattern to withstand the rigors of heavy-haul driving, on- and off-road, while also providing long tread life and even wear.

The design of the RM332 WB tire also includes a protective curb bar on both sidewalls and stone protector ledges in all four circumferential grooves to help resist stone penetrations, the company noted – features that help preserve the casing for retreading.

To promote durability for heavy-haul fleets, the RM332 WB has four heavy-duty, full-width steel belts and comes backed by a Roadmaster warranty that offers two retreads within six years.

“The deep tread and cut and chip resistant compound our engineering team developed for this tire are essential for fleets operating in on- and off-road conditions,” noted Gary Schroeder, Cooper’s director of commercial vehicle and global OEM sales, in a statement.

“Fleets are continually looking for opportunities to gain a competitive advantage and to be most cost-efficient,” he added. “Our RM332 WB tire, which provides long miles to removal and is backed by a strong warranty, can help them attain these goals.”
