The container has wheels (10), each with a tread (14) made of rubber, forming a closed cavity (20) that presents a volume which is greater than the half of total volume of the tread. The tread has an envelope defining the closed cavity, and having an annular wall (15) radially outwards with a constant thickness along a direction parallel to the axis of rotation of the wheel. The tread has an inner annular rib extending into the cavity.
