える恐れがある。Therefore, some spike pins are made of hard rubber. Among the spike pins made of hard rubber, the spike pins are softened at room temperature, but they harden as the temperature gets lower, and they become metallic. A rubber having the property of changing to (1) has already been developed by the inventor of the present application (Japanese Patent Laid-Open No. 2-84459). The spike pin molded from rubber that hardens at low temperatures softens at room temperature and hardens on ice and snow roads, and acts as a spike pin.However, friction with the road surface due to tire rotation and tires due to vibrations The internal heating of the may affect the hardening of the spike pins.

剤で固着することもできる。Means for Solving the Problems In order to solve the above-mentioned problems, a tire for slip prevention according to the present invention is a plate-shaped rubber piece made of a rubber material that hardens at a low temperature, and the upper end surface of the plate-shaped rubber piece is the tread surface of the tire. And is mounted in the tread groove at substantially the same height as. Further, the anti-skid tire of the present invention may be provided with a mounting slot at the bottom of the tread groove, and the lower part of the plate-shaped rubber piece may be mounted in the mounting slot, or the plate-shaped rubber may be mounted at the bottom of the tread groove. It is also possible to fix the pieces with an adhesive.

Since the plate-shaped rubber piece is made of a rubber material that hardens at low temperatures,
Of course, when the outside air temperature does not fall to a low temperature, it does not harden and exhibits normal soft elasticity, and even if the outside air temperature is low, it is attached to the bottom of the tread groove of the tire, so there is snow and ice on the road surface. If not, the heat is transmitted to the mounting portion by the heat generated by the vibration of the tire main body during the running of the tire and the frictional heat with the road surface, and the plate-shaped rubber piece is not hardened.

る。In the case of a snowy road, when ice or snow enters between the tread groove wall and the plate-shaped rubber piece, the plate-shaped rubber piece is cooled and hardened, and the tread rubber of the tire is compressed and deformed by the load of the car. However, the shape of the plate-shaped rubber piece does not change, stabs in snow or ice, and the upper end portion of the plate-shaped rubber piece functions as a traction force during driving and a braking force during braking.
