OVERVIEW

Heavy-Duty Replacement for Miller Trailers

The Miller 278030 is a specialized tire and rim combination engineered specifically for the rigorous requirements of industrial welding trailers. In the MRO and welding sectors, equipment downtime translates directly to lost revenue. This pre-assembled unit minimizes maintenance time by providing a ready-to-install solution for compromised trailer wheels. The assembly includes a robust steel rim fitted with a premium ST175/80R-13 radial tire, eliminating the labor and cost associated with separating tires from rims and re-balancing.

Technical integrity is at the core of this product's design. The Load Range D (LRD) specification is a critical feature, indicating an 8-ply equivalent rating. This provides superior sidewall strength and puncture resistance compared to standard Load Range C tires often found on lighter utility trailers. For welding rigs that are often loaded near their maximum gross vehicle weight rating (GVWR) with generators, cylinders, and tools, this extra capacity provides a necessary safety margin. The radial design further enhances performance by maintaining a flatter footprint on the road, which improves traction and promotes even tread wear over the life of the tire.

Compatibility is key when sourcing replacement parts for fleet equipment. As an OEM replacement part, the Miller 278030 guarantees correct hub fitment and clearance for Miller-manufactured trailers. Improperly sized aftermarket wheels can cause interference with trailer suspension components or fenders. This assembly ensures that the tracking width and load distribution remain within factory specifications. Whether you are refurbishing an older trailer or replacing a damaged wheel on a newer unit, this tire and rim assembly provides the durability and reliability professional welders demand for their mobile operations.
