Cooper Tire & Rubber Company has added two new sizes to its Roadmaster RM272 commercial tire line, which is specifically engineered to withstand the demands of drop-deck trailers. The RM272 is now available in sizes 11R22.5 and 295/75R22.5.
Designed to ward off irregular wear and damage due to curbing, Cooper says the RM272 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 says.
“Tires in this application are arguably the most abused of any in the trucking industry, and we designed the RM272 to withstand this harsh punishment,” says Gary Schroeder, director of Cooper’s truck and bus tire business, which includes the Roadmaster brand. “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.
“Our engineers designed a great tire, backed by a strong warranty and the quality Roadmaster is known for,” adds Schroder. “We know that fleets are continually looking for opportunities to be more cost-efficient, and our RM272 tire can help them to attain this goal.”
