Abstract
A wheel having a plurality of lugs mounted in side-by-side positions forms a circular ring where each of the lugs has laterally extending legs forming a V-shape aligned with a rotational axis of the wheel. The lugs may have an outfacing rib aligned with the rotational axis and a further outfacing rib orthogonal to the rotational axis. A circular tensioning cord or strip may join the plurality of lugs. The lugs may be mutually offset around the circular ring in a sinusoidal pattern.
