PURPOSE: A disposable snow chain is easy to attach and detach and improve the appearance of a tire and reduces noise or vibration. CONSTITUTION: A snow chain is a band type. A protrusive part(3) is formed on the outside(2) of a band. A soft and non-adhesive pad layer made of foamed urethane is formed on the inside(4) of the band to be pushed into the threads of a tire. A metal or high-elastic net(8) is fixed between the inside(4) and the outside(2) of the band to increase tensile strength of the pad. The edge(9) of the band is hardened or has a wire and so on built in to tighten the edge of the band. Both ends of a locking device(5) are pulled to tighten the contact between a tire and the band.
