Abstract
Abstract A hollow wheel is rotatively mounted on a vehicle about an axis of rotation defining an acute angle with the vertical. This wheel comprises a first convex side wall having an outer face defining a circular and axially tapering tread centered on the axis of rotation, and a second side wall spaced apart from and connected to the first side wall to form the hollow wheel. A tube, centered on the axis of rotation, interconnects the first and second side walls to receive an axle. The tread is generally conical and presents a convex cross section. Preferably, the interconnected first and second side walls form a water-tight hollow body presenting buoyancy. The hollow wheel can be used on ground, water and snow.
