8.50-20/1.7 is a common OTR rim specification utilized for underground mining vehicles. Rims of this specification are designed to pair with mining-specific tires, offering superior impact resistance, higher load-bearing capacity, enhanced maneuverability in underground environments, and greater operational stability.
They are particularly well-suited for use in the damp tunnels of underground mines, environments subject to rocky impacts, ramp haulage operations, and high-frequency, continuous-duty applications.
Traction serves as the Original Equipment (OE) rim supplier in China for Volvo, Caterpillar, Liebherr, John Deere, and Doosan.
