Extra-thick, extra-wide rubber or urethane tread wheels are available in a variety of popular sizes for use on industrial trailers and wagons in the 5-ton class and up. The solid tires are chemically bonded to replaceable steel rims, which are "pressed on" to a heavy-duty cast iron center.
Both rubber and polyurethane wheels feature a smooth tread design and sealed tapered roller bearings are standard.
