Goodyear has launched a new addition to its off-highway large haulage product line, the RH-4A+ tyre, which it says is engineered to deliver a lower operating cost per hour and higher productivity in hard rock underfoot conditions.
This tyre features an extra-deep E-4+ tread depth with a high net-to-gross tread pattern and optimised footprint pressure to help provide long hours to removal.
The RH-4A+ is currently available in sizes 59/80R63, 46/90R57 and 27.00R49 through Goodyear’s global network of authorised OTR dealers. It is available in customised casing constructions and with Goodyear’s proprietary tread compounds to meet hauling conditions.
Eric Matson, global OTR field engineering manager 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 optimise productivity and lower their operating costs.”
Field results from global mining customers have shown that the RH-4A+ delivers up to 12 per cent better hours to removal than the Goodyear RM-4B+ tyre.
The new Goodyear RH-4A+ features enhanced sidewall durability and lateral stability with Goodyear’s new Durawall Technology, wider bead design, and wider molded rim width.
The tyre has increased hours to removal and cut protection with its high net-to-gross tread pattern and deep, E-4+ tread depth.
It also features cool operating temperatures from the tread’s centerline blading, shoulder lug pockets, and shoulder lug side notches.
