PURPOSE:To prevent the expansion of a tire chain at the time of travel by hang-stopping an elastic ring and a low expansion quality ring having the same length of circumference with the overall length of the elastic ring at the time of attachment, to the hooks of the fitting rope of the non metal made tire chain. CONSTITUTION:In the case of a non metal made tire chain of a rudder shape 20 being attached to a tire 30, a fitting rope is firstly roped around on the back side of the tire 30, and hooks provided at its both end portions are hung together. Next, a fitting rope 21 is roped around on the front side of the tire 30 and hooks at its both end portions are hung together, and then, hooks 22 fitted to the rope 21 at intervals are hung and stopped at an elastic ring 10, and the tire chain 20 is tightened up by means of its elastic force. And then, a low expansion quality ring 12 is laid together on top of the elastic ring 10, and the ring 12 is hung and stopped at the hooks, and at the time of the high speed rotation of a car wheel, the outward expansion of the tire chain against tensile strength is arrested by the elastic ring 10. |
