FINDLAY, Ohio—Cooper Tire & Rubber Co. added to its Roadmaster line of commercial tires with a new tire designed specifically to withstand the demands of sanitation trucks.
The company's new RM230 WH is an all-position waste-haul tire available in size 315/80R22.5 with load range L. It is an inch wider than its predecessor, with 20 percent larger footprint than any previous Roadmaster waste-haul tire, Cooper said.
“We designed this tire specifically with the steer position in mind, since the life expectancy for many steer tires on sanitation trucks is often gauged in months, not miles,” said Gary Schroeder, Cooper's director of Commercial Vehicle and OEM Sales. “For sanitation operators, tires are often the biggest expense, surpassing even fuel in some severe applications.
“We are confident that customers will see the RM230 WH as an industry leader for this application when the big picture of life expectancy, affordable price and retreadability is considered.”
He noted that the tire's wider footprint “helps evenly distribute the weight on this tire to enhance tread life. When you have up to 10,000 pounds per tire riding on that footprint, and constant scrubbing and curbing, bigger is better.
“Years of development went into this tire, and we anticipate that it will serve our customers' needs extremely well moving forward,” Schroeder added.
The RM230 WH also features a stone protector ledge in the center groove of the tire to help guard against stone penetration, preserving casing retreadability. The tire's four-rib design improves traction, Cooper said, while the RM230 WH is made of a new wear-resistant tread compound designed especially for waste hauling fleets. The tire also features 24/32nds of tread depth to provide more miles—and months—on the job, according to the Findlay-based tire maker.
Cooper said it provides a warranty on the RM230 WH that offers two retreads within six years, and the tire features a high-tensile strength four-belt package to aid in retreadability.
“For waste fleets, steer tire casings provide the life for the drive tires, and trailer tires too if the fleet also runs transfer dump operations,” Schroeder said. “The casing we've developed for this tire, along with the warranty, provide life and cost efficiency beyond the original tread.”
Cooper also recently added a new size—275/70R22.5—to its Roadmaster RM230 HH tire line to meet demands of severe-duty applications, such as logging and mining.
The tire is designed to withstand stone penetration, with 18-ply rating (load range J) construction, tread depth of 22/32nds, cut and chip resistant compounding, and an off-road design with lugs and a stone protector ledge.
Schroeder said 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 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,” Schroeder said. With the deeper tread of the RM230 HH “we can help ward off tire damage from off-road challenges, such as shot rock and tree roots. Plus, our special compounding helps in combating 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 added.
