FIG. 2 is a cross-sectional view of a shape with a sloped plane. FIG. 2 is a cross-sectional view showing that the head A of the steel spike pin is driven into the tread portion of a snow tire so that it is flush with the surface of the rubber portion B of the tread;
The part A indicates that the top of the pin is facing forward in the direction of rotation of the tire. FIGS. 3A and 3B are diagrams showing that the tip of the sloped head plane of the steel spike pin is cut to form a shape with a ground plane. FIG. 4 is a sectional view showing that a hard polymeric chemical material is baked and integrated instead of the steel spike pin. FIGS. 5A and 5B are perspective views showing that the flat part of the head of the spike pin is curved. FIG. 6 is a sectional view showing that the top of the spike pin A has a slight step with respect to the surface B of the tire tread. FIG. 7 is a cross-sectional view of a conventional spike pin. Figure 8 is an enlarged view showing that when the brakes are applied, the tip of the spike pin attached to the snow tire sticks out from the tread surface and bites firmly into the frozen road surface.

Claims

[Scope of Claim for Utility Model Registration] 1 (a) The head of the steel spike pin has a shape with a sloped plane (Fig. 1 A, B) (b) The slope of the steel spike pin Point the top of the flat head (A in Figure 2) toward the front in the direction of tire rotation. Drive the spike pins at regular intervals so that they are flush. The dust-free snow spike tire constructed as described above. 2. The dustless type snow according to claim 1 of the utility model registration claim, which has a shape in which a ground plane is provided by cutting off the tip of a sloped plane of a steel spike pin, as shown in FIGS. 3A and B. spike tires. 3. A dust-free snow spike tire according to claim 1, which uses a hard polymeric chemical material (hard rubber or hard resin) instead of steel spikes. 4. A dust-free snow spike tire as set forth in claim 1 of the utility model registration claim, which has a structure in which, instead of steel spike pins, a hard polymeric chemical material is baked into the tread portion of the tire at regular intervals and integrated. (Figure 4). 5. The dust-free snow spike tire according to claim 1 of the utility model registration claim, in which the flat part of the head of the spike pin is curved (Fig. 5 A, B). 6. The dust-free snow spike tire according to claim 1 of the utility model registration claim (Fig. 6), in which the top of the spike pin is attached with a slight step outward from the surface of the tire tread.
