To simplify mounting and shorten mounting time by integrating a chain part, a tire part and a wheel part instead of a conventional mounting method of putting a chain on a tire and fastening them at a front part with rubber or a fitting.

In the stationary state of a vehicle, hooks D of a chain with hook belts are fitted and fixed to rear (back side) hooks of a tire, and hooks C of the chain with hooks are fitted and fixed to front side hooks of the tire. The hooks C are formed in belt shape, and the tire chain, the tire and a wheel are firmly fixed and tightened at these parts. At the time of actual fitting work, it is desirable to fit the hooks from the upper part of the tire, clockwise in order from the left end.
