り、大きな社会問題となっている。Chains are the most commonly used anti-slip means, but when installing or removing them, the vehicle must be stopped in a safe place, which is often difficult depending on road conditions. Moreover, the operation of the device 19 is extremely troublesome. Therefore, recently, spiked tires in which spike pins are installed in advance have become widely used. However, when driving on snowy or icy roads, these conventional spiked tires lose their driving force and
It exerts braking force, but on the other hand, the spike tires can be used on roads with no snow or roads with little snow, etc.
If a person drives on an unnecessary path, the spike pins will not only scrape off the road surface and cause dust pollution, which will cause serious social problems. This has become a problem.

手段はないが、実際には、タイヤをその都度、通路状況
に適したものと交換することは殆んど不可能である。However, in order to prevent the above problems caused by spiked tires, there is no fundamental solution other than replacing the tires when driving on roads where there is no snow and spike ties are unnecessary. It is almost impossible to replace the tires each time with one suitable for the road conditions.
それ故、特に、春先および初冬の過渡期に問題があった

材を設けるようしたものである。[Means for Solving the Problem] The present invention has been made to achieve the above object, and the means (a) includes a tire having a width approximately equal to the width of the tread portion inside the crown portion constituting the tire. A plurality of spike pin guide holes are formed in predetermined portions of the tread portion, each reaching from the tread contact surface to the +if hollow portion, and each of these spike pins is A support belt having a plurality of spike pins having a predetermined length erected between positions corresponding to the guide holes is inserted into the cavity with the tip of each spike pin inserted into each of the spike pin guide holes. when the tire is fitted into the tire, and when the tire's air pressure is below a predetermined pressure, each of the spike pins maintains a positional relationship slightly set back from the tread contact surface, and when the tire's air pressure is a predetermined value higher than the predetermined pressure. In order to maintain a positional relationship in which each spike pin slightly protrudes from the tread contact surface, an elastic material vJ support member for supporting the support belt is provided in the hollow portion.
［作用１ 本発明は上記手段よりなるので、以下の如く作用する。[Effect 1 Since the present invention comprises the above means, it operates as follows.

In this case, the tip of the spike pin is located in the spike pin guide hole, and the tip of the spike pin maintains a position slightly set back from the tread contact surface, so there is currently no snow on the road, making spiked tires unnecessary. When traveling on a road, by setting the air pressure of the tires to a predetermined pressure (standard air pressure) and driving while maintaining this predetermined pressure, it is possible to travel without damaging the road surface. Next, when driving on snowy or icy roads, the air pressure of the tires that are maintained at a predetermined pressure is further increased to a predetermined value to reduce the tire pressure.
Due to the deformation of the cavity and the expansion of the support belt due to the expansion of the spike pin, the spike pin protrudes slightly from the tread contact surface along the spike pin guide hole, and in order to maintain this state,
By driving with the air pressure set to (Tie) 7, a sufficient anti-soaking effect can be obtained and safe driving is possible.

る。Note that the air pressure of the tie ψ can be easily adjusted at a general gas station. In addition, even in places where there are no gas stations, etc., reducing the air pressure to a specified pressure can be easily done by preparing a gauge and measuring it with the a31=.Also, when increasing the air pressure, However, it only requires a small amount of addition, so if you prepare a small air tank, you can easily do it anywhere.

The tips of the spike pins 9.9 are located at a position slightly retreating from the tread contact surface 3a, and when the air pressure is increased by a predetermined value above the predetermined pressure, the tips of the spike pins 9. state. Therefore, in the former case, only the tread 3 is grounded, and in the latter case, the spike pins 9 are also grounded. Therefore, when driving on a surface where normal driving is possible, such as a snow-free road, if the air pressure is maintained at a specified pressure, the spike pins 9.9 will not touch the ground and cause 10 scratches on the road. There is no risk. On the other hand, when driving on roads where the tires need to be equipped with anti-slip means, such as on frozen roads, if the air pressure is increased by a predetermined value, the tips of each spike pin 9, 9... will protrude slightly from the tread contact surface 3a and the road surface come into contact with. Therefore, sufficient driving force and braking force are ensured on frozen roads and the like, making safe driving possible.
