A wheel for a cart has a static dissipative mechanism. The wheel has a hub that has a central bore for receiving one or more bearings. The outer periphery of the hub has a conductive ring that has projections extending radially outward. The projections are surrounded by a tread material. A conductive wire extends from the central bore where the bearings are, on the outside of the hub, to the conductive ring. A conductive path is provided for the cart through the bearings, the wire, the conductive ring to ground.
