FIELD: transportation.

SUBSTANCE: in a wheel of an amphibian vehicle comprising blade water propulsion units mounted on a hub, blades are made in the form of a set of toroidal pneumatic chambers displaced relative to each other in circumferential direction with an inner diameter each, comparable to diameter of the hub, folded by diameter and fixed by bends on radial driving pins of rings that are coaxially installed on the hub. Besides, rings may have a cross section following the channel bar shape. The ring with radial driving pins may be common in design for the entire set of replaceable toroidal pneumatic chambers of the wheel.
