Cooper adds two sizes to its Roadmaster RM272 commercial tire line, which it says is 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, 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 says this drop-deck application is “arguably the most abused of any in the trucking industry,” so it 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.
