Provided is a pneumatic tire, comprising a plurality of lands, which are segmented by at least one circumferential primary groove which extends along the tire circumference in the track of the tread, and by a plurality of oblique grooves, one end of which opens in the circumferential primary groove, and which extend obliquely with respect to the tire circumference direction in plan view from the one end to another end thereof. The lands further comprise oblique wall parts on lateral wall faces which face the circumferential primary groove and form a portion of groove lateral walls of the circumferential primary groove. The incline of the oblique wall parts increases gradually in the tire circumference direction from the one end to the other end thereof. |
