Abstract: A wheel includes: a first wheel half having a disk portion formed with a central hole that is defined by a hole-defining wall, and a rim extending from a periphery of the disk portion; and a second wheel half having a disk portion connected to the disk portion of the first wheel half, and a rim extending from a periphery of the disk portion of the second wheel half away from the first wheel half. The rims of the first and second wheel halves extend in opposite directions and are adapted for mounting of a tire thereon. The disk portion of the second wheel half is formed with a middle hole and a central bushing that is bent from a periphery of the middle hole and that protrudes axially into the central hole in the disk portion of the first wheel half so as to contact intimately the hole-defining wall of the central hole.
