A skate device, e.g., a skate or skate board, includes a foot support device, e.g., a boot or a board, and a truck assembly for supporting the foot support device. The truck assembly has a first wheel housing mounted in pivotal relation to the foot support device. A first wheel has a first axle mounted to the first wheel housing for rotation about a first wheel axis. A first spring housing is mounted in fixed relation to the foot support device. A centering spring is mounted within the first spring housing and engages the first wheel housing to pivotally urge the first wheel toward a predetermined first center position.
