Abstract: PROBLEM TO BE SOLVED: To enhance the on-ice performance of a studless tire when it is new by forming a number of recesses on the surfaces of the flat parts of the tire having a number of grooved parts formed on its tread so that the tread is sectioned into the flat and grooved parts. SOLUTION: A tread part constituting the tread 1 of a studless tire is made from a rubber material filled with contaminants such as fibers, rubber pieces, and bubbles in a predetermined ratio. On the tread 1, a plurality of main grooves (grooved parts) 2 are formed along the circumferential direction T of the tire and connected together by a number of transverse grooves (grooved parts) 3 extending in the cross direction of the tire. Thus the tread 1 is sectioned into a number of blocks (flat parts) 4 defined by the main and transverse grooves 2, 3 and the grooved parts 2, 3. In this case, a number of recesses 6 are formed on the surfaces of the blocks 4. Thus the edges of the recesses 6 are formed on the block surfaces to provide an edge effect on ice to allow the tire to show the required on-ice performance even when new.
