SRW TBR rims are commercial truck and bus wheel components designed for single rear wheel configurations on heavy-duty vehicles. These steel or aluminum rims are engineered to support TBR (Truck Bus Radial) tires, which feature all-steel wire construction for superior load-carrying performance. TBR rims are typically manufactured to handle high load capacities, with dual load index ratings for single and dual wheel applications, and are designed for various commercial vehicle segments including long haul, regional haul, and urban delivery services. The rims must comply with strict load and inflation limits set by manufacturers and are available in various sizes such as 22.5 and 24.5 inch diameters. These components are essential for commercial vehicles requiring reliable performance under heavy loads and demanding road conditions, offering durability and safety for truck and bus operations.
