Spike tire from which spikes appear only in slip generation

Abstract

Abstract PURPOSE:To suppress the breakage of a road surface and slip of a tire by installing a slide suppressing frame through a supporting member in swingable ways onto the tread surface of a tire and allowing a frictional body and a spike which are installed onto the slide suppressing frame to selectively contact the road surface. CONSTITUTION:A supporting rod 1 is installed onto the tread surface of a tire, and an adjusting rod 2 is installed in free advance and reverse inside the supporting rod 1. A slide suppressing frame 3 is installed in swingable ways at the top edge of the adjusting rod 2, and a spike 4 and a frictional body 5 are installed at the both edge parts and the center part of the slide suppressing frame 3. Therefore, in the ordinary case when a tire rolls on a dry paved road surface, etc., the slide suppressing frame 3 is held in the horizontal state, and the frictional body 5 is allowed to contact the road surface, and a proper grip force for the road surface is obtained. When the tire slips on an ice snow road surface, etc., the spike is allowed to bite into ice snow, etc. by swinging the slide suppressing frame 3, and slip is surely prevented.
