Cooper Tire & Rubber Company has added a new size to its Roadmaster RM230 HH tire line to meet the demands of severe-duty applications.
The Roadmaster RM230 HH tire is designed to withstand stone penetration, with 18-ply rating (load range J) construction, tread depth of 22/32-in., cut and chip resistant compounding, and an off-road design with lugs and a stone protector ledge, the company says. 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, the company says.
“We’ve seen first hand 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,” says Schroeder. “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, Cooper says.
“The tire also comes with a six-year, two retread warranty,” says Schroeder. “It demonstrates the confidence we have in this tire.”
