A tread portion includes land portions partitioned by circumferential grooves extending in a tire circumferential direction and lateral grooves extending in a tire width direction. At least one land portion comprises an annular sipe. A surface of a portion of the land portion surrounded by the annular sipe includes at least one inner side inclining face that inclines toward the annular sipe. A surface of a portion of the land portion along a periphery of the annular sipe includes at least one outer side inclining face that inclines toward the annular sipe. The inner side inclining face and the outer side inclining face are disposed so as not to be opposite each other. A step is formed between a first edge of the annular sipe of the inner side inclining face or the outer side inclining face and a second edge of the annular sipe opposing the first edge. |
