Covering of vehicle tires withlight-alloy rims during prolonged transportation

Cover for vehicle wheels with light-metal rims during protracted transport, comprising:

• a round, closed and inherently rigid film moulding with which an outward-facing side of one of the vehicle wheels is covered, said moulding engaging over the outer face of a light-metal rim beyond a rim flange in a surface-covering manner and being fastened centrally to the vehicle wheel in recesses of the latter by elevations integrally formed in the film moulding and corresponding to the recesses as negatives of the shape of the latter,
• a cylindrical holding connection piece in the center of the film moulding which extends axially towards the vehicle wheel and corresponds in diameter to a centering bore of the rim and which projects into the centering bore of the vehicle wheel under prestress, and
• a circumferentially extending row of catch noses on a circumference of the holding connection piece, which catch noses form a positive connection with the rim hub,
• wherein the catch noses on the circumference of the cylindrical holding connection piece in the center of the film moulding are held at least within a clearance profile of the circumferential groove made in the inner surface of the centering bore,
• wherein the cylindrical holding connection piece in the center of the film moulding carries, on its circumference, a plurality of axially running grooves which are restricted to an axial region of the holding connection piece which lies axially between the catch noses and a base of the holding connection piece,
• wherein the cylindrical holding connection piece in the center of the film moulding carries, on its free end face, only a radially inward-projecting reinforcing flange, the radial width of which corresponds approximately to 8 to 12 times the wall thickness of the film moulding,
• wherein the film moulding is designed with a wavy cross section in a shield part covering the outer face of the light-metal rim and has a plurality of circumferential beads and circumferential grooves adjoining one another in a wavy manner, the center line of the circumferential beads and circumferential grooves adjoining one another in a wavy manner likewise being arcuately curved axially outwards in the shield part, covering the rim outer face, of the film moulding itself, and
• wherein the radially innermost circumferential bead of the shield part merges via a cone frustum into the cylindrical holding connection piece, a narrow axially perpendicular collar being arranged between the cone frustum and said holding connection piece.
