PURPOSE: An automatic spike pin snow tire embedding an ultrasonic generator is provided to project automatically a spike pin on the surface of the tire on snowy or frozen roads by a wireless remote controller and to destroy a coating phenomenon generated by a road surface and the rotational speed of the tire by generating sonic vibration on the surface of the tire by the ultrasonic generator. CONSTITUTION: Four ultrasonic generators are fixed in the center of a tire wheel in a tire. Plural sonic vibrating devices are inserted in a tire rubber layer to maximize vibration by elasticity of the rubber. A coating phenomenon caused by rotation of the tire on rainy days is destroyed by 30,000¯32,000 times of vibration. A spike pin(1) is operated by a wireless remote controller and protruded on the surface of the tire to prevent the tires from skidding.
