1. A wheel assembly, comprising:
a rim having a rim peripheral portion and defining an axis of rotation; a round rib surrounding and radially spaced apart from the rim; a resilient member disposed around the rim and engaging the round rib, the resilient member including a resilient member peripheral portion and one or more protruding portions, wherein the resilient member peripheral portion is held apart from the rim by the round rib, and the one or more protruding portions protrude radially toward the rim; and a plurality of tying members, each tying member connecting one of the one or more protruding portions of the resilient member to the rim, such that the rim is resiliently held in relation to the round rib at least in part by tension in the one or more protruding portions of the resilient member. |
