A tire rim of a motor vehicle includes a substantially cylindrical body for holding a tire, and a hub connected to the body through radial members, and has an outer face facing, in use, the outside of the vehicle, and an opposite inner face. At least one elongate flexible element associated with the rim can reach a resting configuration within the rim, and a working configuration, extended with respect to the resting configuration, of such a length as to allow the tire to be surrounded, in which each flexible element is wound around the tire to form a snow chain. The rim includes at least one retaining member at a zone of its inner face, to be engaged by a portion of a flexible element in its working configuration.

The present invention relates to an automotive tyre non-skid device for snowfields to increase adhesion to pavement covered with ice or snow, in particular to a diagonal bead chain stress reducing pinch plate and a diagonal bead chain. Through configuration of stress reducing pinch plates and stress reducing transition chains disposed on two sides of a second connecting assembly, concentrated stress at the connector roots of steel cables of the stress reducing transition chains are isolated, dispersed and relieved, and the service life of the steel cables are prolonged. At the same time, the present invention has the advantages of simple structure, stable performance, convenient modification and low manufacturing cost.

This invention discloses an automatic locking device for snow anti-skid chains. Wherein the snow anti-skid chain comprises a ratchet wheel lock catch and a anti-skid chain; the anti-skid chain is respectively fixed at the buckle and the outer part of the housing aforesaid, and extends towards three directions. The ratchet wheel lock catch is used to make the anti-skid chain to attach to automobile tires firmly and is controlled by pressing two buttons on its lower side, which is different from existing operational actions of braking off and twisting. The pressing action is simple and available for one hand operation. The overall structure is simple and reliable, conforming to use habits of control actions by users.

A sleeve for covering vehicle wheels includes a fabric band having an annular arrangement and therefore with a circumferential path as a result of the annular geometry, the band having such proportions and being enabled to cover and surround an external region of a wheel of a vehicle. The fabric band has a central area along its circumferential path and at least one lateral area adjacent to the central area following the same circumferential path. The at least one adjacent lateral area of the band has a surface density value lower than the surface density value of the central area of the same band. The band also presents a textile or fabric continuity in the mutual contact between its central area and at least one adjacent lateral area, the band being formed in one piece or textile body.

A tire grip enhancing assembly includes a covering for removably positioning on a tire. The covering comprises a flexible material and has a first lateral wall, a second lateral wall and a perimeter wall that is attached to and extends between the first and second lateral walls. Each of the first and second lateral walls has an annular opening extending therethrough. A plurality of raised members is attached to and extends away from the perimeter wall. A pair of bands is provided. Each the annular opening has a perimeter edge has one of the bands attached thereto. Each band is comprised of a resiliently stretchable material.

A method of mounting a vehicle tire chain on a vehicle tire by draping the chain on the tire and connecting the free ends of the chain with suitable temporary straps to form temporary loops on the tire and rolling the wheel a quarter to a half of a revolution to complete the mounting of the chain, and producing a high quality mounting using special tension sources and stabilizers to migrate residual chain slack to the side chain closure device during a short travel to a stop to re-hook the chain to a suitable operating chain tension.
