A wheel assembly (22) includes a rigid wheel and an airless tire (32) configured to present some performance characteristics of a pneumatic tire. The wheel includes a pair of radially outermost axially spaced rim portions(42, 44), each rim portion including a transversely flat outer surface extending at least partially around the circumference of the wheel. The tire is mounted on the wheel such that the tire engages the outer surfaces of the rim portions of the wheel. A central portion of the tire is configured to flex inwardly between the rim portions of the wheel in response to ground engaging pressure, thus minimizing ground penetration and soil disturbance during use. |
