A transit wheel is disclosed comprising a body having a bore through the center thereof, a hub about the bore extending through a web to an outer portion, and an annular rim having a circular inside surface disposed against a circular outside surface of the outer portion. The inside surface of the annular rim and the outside surface of the outer portion are each provided with a circumferential groove, which grooves are substantially aligned when the annular rim is disposed against the outer portion. The transit wheel further includes a damping rod formed into a ring and disposed within the aligned grooves, with the ring traversing at least 95% of the circumference of the groove. |
