What is claimed is: 1. A wheel comprising:an inner assembly including a rim generally formed around a hub, the rim including a cross-section having a first side, a second side generally opposite the first side, a ground-facing surface, and a hub-facing surface, wherein the rim includes a first plurality of apertures through the first side of the rim and a second plurality of apertures through the second side of the rim, the first plurality of apertures radially offset from the second plurality of apertures; andan outer assembly comprising a material different from that of the inner assembly, the outer assembly mechanically coupled through the rim at the first and second sides of the rim, the outer assembly at least partially covering the ground-facing surface of the rim and extending radially inward of the hub-facing surface of the rim, the hub-facing surface of the rim being generally devoid of the material of the outer assembly.
