PURPOSE:To secure the on-ice performance and the eccentric abrasion resistance of a tire having block patterns. CONSTITUTION:On a tread surface, a block pattern consisting of blocks 3 divided by the main grooves 1 extending in the tire peripheral direction and subgrooves 2 crossing with the main grooves 1, and thin cut parts are formed on the block 3. The block 3 is divided into three parts by the thin grooves 4 in the tire width direction which has less groove width and groove depth than those of the subgroove 2, and thin cut-in part 5 in the tire width direction are each formed on the respective into-three divided small blocks 3s. |
