Cooper Tire has added the Roadmaster RM351 HD to its commercial tire lineup, designed for mixed service applications such as construction, logging and mining operations.

The tire is designed for both on- and off-road driving and comes in two sizes: 11R22.5 and 11R24.5, in load range H.

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

Tie bars between the outside lug and the shoulder, along with shoulder grooves that are linked and interlocked, help ward off tire squirm and irregular wear. The sidewall is extra thick with a curb bar protector to help protect the casing from cuts and scrubbing.

For traction and durability, 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.

The Roadmaster RM351 HD’s casing features a four-belt steel design construction. Cooper provides a six year, two retread warranty on the RM351 HD.
