Goodyear Tire and Rubber in November 2020 introduced the RH-4A+, a new addition to its off-highway large haulage product line.
The tire, the company said, is its best haulage tire for long hours and higher productivity in hard rock underfoot conditions, paired with lower operating costs per hour.
It features an extra-deep E-4+ tread depth with a high net-to-gross tread pattern and optimized footprint pressure. It also has enhanced sidewall durability and lateral stability with Goodyear’s Durawall Technology, wider bead design and wider molded rim width.
Eric Matson, global OTR field engineering manager, said that its field results from global mining customers have shown the RH-4A+ can deliver up to 12% better hours to removal than RM-4B+.
The RH-4A+ is available in sizes 59/80R63, 46/90R57 and 27.00R49 through its worldwide network of OTR dealers. It is also available in customized casing constructions.
