Cooper Adds Tire Sizes for Drop-Deck Trailers

Cooper Tire & Rubber Co.

Cooper Tire & Rubber Co. added two sizes to the Roadmaster RM272 commercial tire line, which is engineered to withstand the demands of drop-deck trailers, and noted tires in this application are arguably the most abused of any in the trucking industry.

The RM272 now is available in sizes 11R22.5 and 295/75R22.5, the Findlay, Ohio-based company said.

The tire line features a four-belt steel casing and has a slightly rounded tread footprint, along with a reinforced shoulder to help withstand extreme side forces. Its tread compound has been formulated to provide optimum balance between resistance to side forces and maximum wear, the company said.

“We looked at a variety of tread profiles that could minimize the load on the shoulder rib and worked toward a design that distributed the load more evenly across the entire footprint so that the shoulder takes on less of the lateral forces,” Gary Schroeder, Cooper's director of truck and bus tire business, said in a statement.
