FIG. 1 is a sectional view of a cylindrical protrusion provided on the outer surface of the tire, and FIG. 2 is a plan view. A large number of cylindrical protrusions 10 are provided on the ground contact surface of the tire, and the internal space thereof has a pyramid shape that widens toward the ground contact surface and opens at the edge. The cylindrical protrusion 10 is preferably cylindrical. The array of the cylindrical projections 10 may be arranged in a staggered manner as shown in FIG. 3, but it is preferable to form a linear shape in the tire width direction as shown in FIG. Further, as shown in FIG. 4, it is preferable to provide linear projections 12 that also extend in the tire width direction between the cylindrical projection rows that are linearly arranged in the width direction. The linear protrusions 12 need only extend in the width direction of the tire and may be provided in a zigzag shape. A concave groove (not shown) having an appropriate depth may be provided on the upper surface of the linear protrusion 12. The number of tubular projection rows and the number of linear projection rows are one for two tubular projection rows.
The rows may be arranged, or the arrangement thereof may be appropriately determined depending on the driving feeling or the like so that a better driving feeling can be obtained. The tire is not particularly limited in rubber quality, but it is preferable to use a soft rubber that is hard to be hardened even at a low temperature like a conventional studless tire.

クッションにより好適な走行感を得ることができる。As described above, according to the present invention, since a large number of tubular projections 10 are provided on the ground contact surface of the tire, the tubular projections bite into the snow surface, and the driving force and the braking force on the snow surface are effectively exhibited. It Further, since the cylindrical projection 10 is formed so as to have a conical shape in which the internal space spreads toward the ground contact surface as described above, when the outer surface of the tire is grounded on a frozen surface or the like, air in the internal space is expelled, thereby The protrusions act like suction cups, and attract the ground contact surface. Therefore, when traveling on a freezing surface or the like, the effect of preventing the initial movement of the slip can be achieved in the range of 360 °. This prevention of initial movement is extremely important because slippage causes the steering wheel to lock in the initial movement direction and renders the steering wheel ineffective. In addition, since the cylindrical projection 10 has an adsorbing action even when the vehicle starts on a slope or on a icy surface, the wheels can be prevented from idling and the vehicle can start smoothly. It is important to prevent the initial slip during this start as well.Everyone has experienced the situation that once one wheel slips due to the action of the diff and the other wheel starts slipping, the other wheel cannot start at all. However, according to the present invention, this initial slip can be effectively prevented. Since the shape of the internal space of the cylindrical protrusion 10 is provided in the shape of a cone that spreads toward the ground contact surface as described above, even if snow enters the internal space, it can be naturally eliminated during traveling. As described above, the cylindrical projection 10 has an adsorption effect,
Since this suction action has a slip preventing effect in the range of 360 °, that is, in all directions, the array of the cylindrical projections 10 can be made linear in the tire width direction. With such an arrangement, snow is scratched by the rows of the cylindrical projections 10, so that the driving force on the snow surface at the time of starting and stopping can be further increased, and braking and starting can be performed more suitably. Sliding in the lateral direction by providing the tubular protrusion 10 in the width direction can be prevented by the suction action of the tubular protrusion 10 as described above. Moreover, by providing the linear protrusions 12,
Further, the snow scratching force can be increased, and braking and starting can be more suitably performed. Furthermore, even when driving on general roads,
The influence of the cylindrical projection 10 is not so great, and the rubber cushion provides a suitable running feeling.
