A pneumatic tire which can enhance performance on snow while assuring performance in wet or dry condition is provided. A plurality of inclined lateral grooves 16 which extend from the tread edge 12E toward the tire equatorial surface CL, being inclined with respect to the tire circumferential direction, are arranged in the tread 12 to establish the rotation directionality, whereby high performance in wet condition is obtained. In traveling on snow, the snow is got into the inclined lateral grooves 16, resulting in a force for shearing the snow column being obtained, thus basic performance in traveling on a snow covered road surface is provided. In the land portion 18 between inclined lateral grooves 16 adjoining in the circumferential direction, convexly curved line fine grooves 20 and sipes 22 are formed on the treading-in side, whereby a great edging effect is obtained in treading in the snow, which can enhance traction performance on snow. In addition, in the land portion 18, the kicking-out side is provided with less grooves than the treading-in side, having a higher rigidity, thus the land part rigidity as the entire land portion is assured, resulting in maneuvering performance in wet or dry condition being ensured.
