A wheel includes a supporting frame, with a central portion having a center around which the wheel can turn, and a plurality of radial portions extending from the central portion angularly displaced with each other. A housing seat is delimited between two adjacent radial portions. A movable element is radially displaceable between a first working position located at a maximum distance with respect to the center, and a second working position located at a minimum distance with respect to the center of the central portion. The radial portions and the movable element have respective distal sections, with respect to the center, curved with a curvature radius corresponding to the curvature radius of the wheel and being flush with each other. A locking element is displaceable between one locking position, wherein it abuts on the movable element and prevents the radial displacement thereof, and one unlocking position, wherein it allows the radial displacement of the movable element toward the second working position. A returning element of the movable element between the supporting frame and the movable element is configured to bring the movable element back into the first working position. A band made of an elastically deformable material surrounds the distal sections of the plurality of radial portions and the movable element, at the circular perimeter of the wheel.
