Abstract: Most of the currently used and sold snow chains cause severe vibration and noise when mounted on a vehicle, so vehicle drivers avoid using them because of the vibration, poor ride quality, noise, and resultant discomfort even if they need to mount the snow chains for driving. Then, in many cases, they face inevitable accidents on a frozen or snowy road. In addition, there are some snow chains with minor vibration but they have considerably poor functions as snow chains'. Therefore, the present invention has been devised and made, and if the snow chain of the present invention is unable to be mounted on your tires because of slight differences, you can mount the snow chain by increasing or decreasing the tire air pressure. In addition, the part coming in contact with the ground surface has a sawtooth shape, so there is no concern over damage to the road surface at all. However, in winter, the air temperature is in general low, so the temperature on the road surface also declines, and it is expected that the road surface would keep a higher strength than usual. In addition, since the sawtooth-shaped parts successively come in contact with the ground surface, so the load coming in contact with the ground surface is dispersed. Accordingly, it is determined that the road surface would not be damaged. Lastly, it is sincerely hoped that all drivers across the globe could comfortably drive their vehicles on the snowy and icy roads in winter by using the present invention.
