た。The spring coil manufactured by the conventional technology and the compounding component also has a running speed of 5% on snow.
As long as the vehicle runs at a speed of 5 km / hr or less, a travel distance of approximately 800 to 1000 km can be secured until it is discarded due to wear or breakage, etc., compared to a chain chain defined by JIS conventionally used in this field. Can maintain the traveling distance of 3 to 4 times, so that the advantage is recognized even in consideration of the price and the like.

従来の寿命に比較して、著しく短いものとなる。In such a case, most of the traveling inevitably travels on a highway on a snow-free road surface in front of Japan. In this case, the anti-slip attached to the outer circumference of the tire makes a movement that hits the ground due to centrifugal force, but when running at high speed, this force increases at an accelerated rate and it is originally used on snow It is significantly different from the conventional conditions considered to be used, and is significantly shorter than the conventional life used on snow.
