Abstract
A wheel comprises a hub 11 and a plurality of ground-engaging pads 16 disposed around and coupled to the periphery of the hub by radial studs 17. Each pad is capable of at least a limited degree of angular displacement about the axis of its stud 17 whereby the hub may turn through such angle relative to any pad currently in ground contact. A resilient stop 30 is associated with each pad to return each pad to its undisplaced position when the pad has moved out of contact with the ground. In an alternative embodiment a resilient member between the hub and the pad serves to both limit angular displacement and return the pad to its undisplaced position.
