ABSTRACT:
The present invention relates to snow tire spikes for use with automobiles adapted to run on frozen road surfaces or on snow. The snow tire spike comprises a spike body formed by using a ceramic stock molded by pressing with dies and a flange made of plastics which coats at least the end part of the spike body which is attached to the tire. The anchoring part formed at the attaching end of the spike body has a larger diameter than the opposite end of the spike body, but has a diameter smaller than 1.5 times that of the latter. This larger diameter part is wholly coated with plastics, and is unified with the outer circumferential part of the spike body through a smoothly tapered or arc-shaped joining surface.
