Trailer Wheel

A trailer wheel is a specialized wheel assembly designed to support the load of a trailer and transmit forces between the axle and the road surface, which includes the rim and hub, studs, lug nuts, and sometimes an integrated brake hub. These wheels vary in diameter—common sizes range from 8″ to 16″—and are built with load ratings that must match or exceed the trailer’s Gross Vehicle Weight Rating (GVWR) to ensure safety and avoid overloading. Trailer wheels bolt to the axle hubs using standard patterns—often 4‑, 5‑, or 6‑lug—and are aligned using pilot centers or hub-centric designs to maintain proper tracking and reduce vibration. Wheels used on brake-equipped trailers may contain integrated brake drums or disc mounting surfaces, enabling braking functionality.
