Cooper Tire & Rubber Company added a new size to its Roadmaster RM230 HH tire line to meet the demands of severe-duty applications, such as logging and mining.The company said the tire is designed to withstand stone penetration, with 18-ply rating (load range J) construction, tread depth of 22/32-inch, cut and chip resistant compounding, and an off-road design with lugs and a stone protector ledge. The new size available is 275/70R22.5.According to Gary Schroeder, Cooper’s director of commercial vehicle and OEM sales, the new size offering was inspired by the tire maker’s visits with Canadian loggers, who expressed a need for a robust trailer tire.“We’ve seen firsthand in the field that when it comes to severe duty, loggers and miners put their trailer tires to the test, and as a result, tire life expectancy can be shortened,” Schroeder said. “Our new RM230 HH has a very deep tread at 22/32nds while most highway trailer tires are in the range of 12/32nds to 16/32nds. With the deeper tread, we can help ward off tire damage from off-road challenges, such as shot rock and tree roots. Plus, our special compounding helps in combatting scrubbing once the tire is running on pavement.”The RM230 HH features a high tensile strength four-belt package to help promote multiple retreads, the company said. “The tire also comes with a six-year, two retread warranty,” Schroeder said. “It demonstrates the confidence we have in this tire.”
