The wheel comprises a central portion attachable to a vehicle hub and a rim arranged radially outside the central portion for supporting a wheel tire. The central portion has a series of cavities configured to receive a corresponding adapter. A cavity of the series of cavities has a through hole. The through hole is aligned in an alignment direction for alignment with a through hole of a corresponding adapter for traversal by a mounting element to attach the central portion to the vehicle hub. The cavity is configured to receive the corresponding adapter in a unique rotational position with respect to the alignment direction. The cavity includes first and second cylindrically shaped and axially aligned volumes. The first volume is bounded by a first receiving wall portion that extends substantially parallel to a front side surface of the central portion. The second volume extends from the first volume towards a back side surface of the central portion. The second volume is located radially within a radial outer periphery of the first volume. | 12-12-2013 |
