The present invention relates to an antiskid tire which prevents skid by protruding spikes from the surface of the tire when the surface of a road is slippery, improves user convenience by inserting the spikes into the tire when the surface of a road is smooth, and extends the life span of the tire. The present invention comprises a plurality of spikes inserted to protrude from a main tire toward the surface thereof; a supplementary tire contained in the main tire to contact with the inner parts of the spikes to protrude the spikes out of the main tire if air is injected; and a wheel rim having a first support protrusion and a second support protrusion formed to support the main tire and the supplementary tire along the circumference at an edge part and at a central part, and having a first air injection hole and a second air injection hole formed in the direction of a central axis from the edge part and the central part to inject or discharge air from the main tire and the supplementary tire. |
