PROBLEM TO BE SOLVED: To provide a pneumatic tire having improved crack resistance of the tire while securing on-ice performance of the tire.SOLUTION: Groups of small blocks consisting of small blocks divided with small grooves and arranged densely are arranged in at least a part of the tread surface of the tread of a tire, and the small blocks is of a polygonal shape higher than pentagonal and have two width direction sides extending along the tire width direction and two sipings extending along the tire width direction and separating from each other in the tread circumferential direction. Taking the tire width direction width of the width direction side on one side in the tread circumferential direction as 'a' and the tire width direction width in the width direction side on the other side in the tread circumferential direction as 'b', the tire meets the condition a>b. |
