Approved Rim Width: 8.5 inches (Provides optimal sidewall profile and minimizes bead stress).
Nominal Rim Diameter: 20 inches.
Wheel Design: Multi-piece Tube-Type (TT) (Typically a 3-piece lock-ring design to accommodate heavy-duty split-rim operations).
Target Tire Size: 12.00R20 (Can also host 11.00R20 or 10.00R20 in some fleet configurations)
Features
Heavy-Duty Load Capacity: Engineered to handle massive burdens, with individual steel rim weight capacities frequently reaching up to 3,800 kg (approx. 8,377 lbs) to support high ply-rating tires.
Multi-Piece Tube Design: Typically features a 2-piece or 3-piece split-rim configuration. This structure allows for manual tire mounting and tube replacement in remote locations (like mines or logging sites) without requiring complex automated tire-changing machinery.
Structural Material and Welding: Manufactured using high-strength special steel to resist severe impact and prevent deformation under load. Premium rims utilize advanced flash-butt and submerged arc welding techniques to secure uniform, solid, and structural-grade seams.
Precision Dynamic Balance: Many leading suppliers employ precision spinning machines to guarantee uniform spoke and rim thickness. This delivers excellent dynamic balance, reducing high-speed vibrations and irregular tire wear
