AKRON — Goodyear is expanding its RH-4A+ haulage tire lineup with the addition of a new size, 40.00R57.
Goodyear said the tire line, initially launched last fall, was engineered to deliver a lower operating cost per hour and higher productivity in hard rock underfoot conditions.
According to the tire maker, the benefits of the RH-4A+, 40.00R57 tire are:
- Increased hours to removal with its high net-to-gross tread pattern and extra-deep E-4+ tread depth; and
- Cool operating temperatures from the tread's centerline blading, shoulder lug pockets and shoulder lug side notch.
Eric Matson, global OTR field engineering manager at Goodyear, said the size has become the company's dominant fitment on 200-ton trucks, such as the Caterpillar 789.
"With a higher TKPH and load carrying capacity, the new Goodyear RH-4A+ tire size is a great option for customers who have converted their 789 fleets to this larger tire," Mr. Matson said.
The Goodyear RH-4A+ is available in sizes 40.00R57, 59/80R63, 46/90R57 and 27.00R49 through Goodyear's authorized OTR dealer network. It is available in customized casing constructions and is made with Goodyear's proprietary tread compounds.
The tire is part of Goodyear's Total Mobility platform of trusted products, reliable services and tire management solutions.
