Abstract:
In a pneumatic tire, a land portion includes a chamfered portion formed on an edge portion of the land portion on a ground contact edge side, and a lug groove and a narrow groove disposed correspondingly to the chamfered portion. The chamfered portion is formed on the edge portion on a ground contact edge side, and has a chamfered width that increases toward a circumferential direction in the road contact surface of the land portion. The lug groove terminates in the land portion on one end, and is opened to a central portion of the chamfered portion in a longitudinal direction on the other end. The narrow groove is opened to an edge portion of the land portion on an equatorial plane side on one end, and terminates in the vicinity of a maximum width position of the chamfered portion on the other end.
