The Goodyear RH-4A+ off-highway tyre features an extra-deep E-4+ tread depth with a high net-to-gross tread pattern and optimized footprint pressure to help provide long hours to removal.
Other features of the tyre include enhanced sidewall durability and lateral stability with Goodyear’s new Durawall technology, wider bead design, and wider molded rim width; and cool operating temperatures from the tread’s centerline blading, shoulder lug pockets, and shoulder lug side notches.
The RH-4A+ is currently available in sizes 59/80R63, 46/90R57 and 27.00R49 through Goodyear’s global network of authorized OTR dealers. It is available in customized casing constructions and with Goodyear’s proprietary tread compounds to meet hauling conditions.
Eric Matson, global OTR field engineering manager, Goodyear, said: “Low operating cost per hour is an important requirement for mine operators. 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 RH-4A+ provides these benefits to help mining fleets optimize productivity and lower their operating costs.”
“Complimenting the RH-4A+ is Goodyear’s EMTrack tyre performance tracking software, giving operators the ability to track the tyre’s properties to reduce operational costs. With EMTrack, mining operators can track the performance of their tyres, including the new RH-4A+, in order to project timing of rotation, replacement and help to manage their inventory,” he added.
