1. A pneumatic snow tire comprising:
a block that is provided at a tread, and that is demarcated by mutually intersecting main grooves respectively extending around a tire circumferential direction and along a tire width direction; a first step portion that extends along a side wall portion at one tire circumferential direction side of the block, and that has a height from a groove bottom of the main groove, where the one side wall portion is present, which is lower than a tread face and higher than the groove bottom; and a second step portion that extends along a side wall portion at another tire circumferential direction side of the block, that has a height from a groove bottom of the main groove, where the other side wall portion is present, which is lower than the tread face and higher than the groove bottom, and that has a smaller width than the first step portion. |
