The Goodyear Tire & Rubber Company has added the RH-4A+ to its off-highway large haulage line.

The new tire features an extra-deep E-4+ tread depth with a high net-to-gross tread pattern and optimized footprint pressure, as well as other features, including:

• Enhanced sidewall durability and lateral stability with Goodyear’s new Durawall Technology, wider bead design, and wider molded rim width

• 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,” said Eric Matson, global OTR field engineering manager. “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 RH-4A+ is currently available in sizes 59/80R63, 46/90R57 and 27.00R49, and in customized casing constructions and with Goodyear’s proprietary tread compounds to meet hauling conditions
