Cooper Tire & Rubber Co. has added two new sizes to its Roadmaster RM272 commercial tire line for drop-deck trailers, with the new sizes 11R22.5 and 295/75R22.5.
Designed to ward off 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 company said.
“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, 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. 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.”
