Cooper Expands Commercial Tire Lineup

Cooper Tire added the Roadmaster RM351 HD tire to its commercial tire lineup.

The tire is engineered for mixed-service applications such as construction, logging and mining operations and on- and off-road driving. It comes in sizes 11R22.5 and 11R24.5 in load range H.

The Roadmaster RM351 HD is an inch wider than its predecessor, the RM300 HH, with a 20% larger footprint. Coupled with its deep 32/32nds tread depth, it provides up to 25% more miles to removal — depending upon the application, according to Findlay, Ohio-based Cooper Tire.

“By going wider, we spread the weight over the tire to gain better mileage while also improving traction,” Gary Schroeder, executive director of Cooper’s global truck and bus tire business, said in a statement.

The tire features five lugs that have an open pattern to minimize stone holding while enhancing traction. Stone ejector ledges, coupled with angled grooves, also help prevent stone drilling.

“That’s a key feature of the tire as it will be used off-road where sharp stones can be a tire’s worst enemy if they’re allowed to drill into the casing. The way we designed this tire helps preserve the casing for multiple retreads,” Schroeder added. — Transport Topics
