AKRON — Goodyear is rolling out an extra-deep E-4+ tread depth OTR radial, the RH-4A+, that it considers its "best haulage tire for long hours to removal in hard rock underfoot conditions."
The tire combines the deep tread depth with a high net-to-gross tread pattern and optimized footprint pressure, which Goodyear claims yields a tire that offers "lower operating cost per hour and higher productivity in hard rock underfoot conditions."
The RH-4A+ is available in sizes 59/80R63, 46/90R57 and 27.00R49.
Benefits and features include enhanced sidewall durability and lateral stability with Goodyear's "Durawall" technology. The tire also has wider bead design and wider molded rim width.
Goodyear promises increased hours to removal and cut protection with the tread pattern and depth as well as cool operating temperatures from the tread's centerline blading, shoulder lug pockets and shoulder lug side notches.
"Low operating cost per hour is an important requirement for mine operators," Eric Matson, global OTR field engineering manager, said.
"Customers also require other performance benefits, such as a tread and casing that together deliver long hours to removal, resistance to cutting, and excellent traction in severe, hard rock underfoot conditions. The new RH4A+ provides these benefits to help mining fleets optimize productivity and lower their operating costs."
The tire is available in customized casing constructions and with Goodyear's proprietary tread compounds.
"Complementing the RH-4A+ is Goodyear's EMTrack tire performance-tracking software, giving operators the ability to track the tire's properties to reduce operational costs," Mr. Matson said.
"With EMTrack, mining operators can track the performance of their tires, including the new RH-4A+, in order to project timing of rotation, replacement and help to manage their inventory."
