Cooper Tire & Rubber Company has added two new sizes to its Roadmaster RM272 commercial tire line, designed to withstand the demands of drop-deck trailers.
The RM272 is now available in sizes 11R22.5 and 295/75R22.5. Designed to defend against irregular wear and damage due to curbing, 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.
The RM272’s tread compound was formulated to be balanced between resistance to side forces and protection against wear.
“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,” said Gary Schroeder, director of Cooper’s truck and bus tire business. “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.”
