Abstract: A pneumatic tire 1 having excellent on-snow performances improved with maintaining steering stability and uneven wear resistance and including tread portion 2 having a pair of crown circumferential grooves 3 which extend continuously in the tire circumferential direction on both sides of tire equator C and have groove edges, one edge 3m extending in such a zigzag form that italic L-shaped groove edge segments 3s are continuously connected to each other in the circumferential direction, and the other edge 3n extending in such a wavy form that circular arc groove edge segments 3o each having a circular arc shape convex toward a groove center are continuously connected to each other in the circumferential direction, wherein each of the italic L-shaped groove edge segments 3s comprises long side part 3c inclined at an angle of 1 to 20° with respect to the circumferential direction, and short side part 3t having a circumferential length smaller than that of the long side part 3c and inclined in the opposite direction to the long side part 3c with respect to the circumferential direction.

Abstract: To make it possible to enhance uneven wear resistance while maintaining drainage performance, a pneumatic tire includes a left-right asymmetric tread pattern having a designated mounting orientation with respect to a vehicle. Vertical grooves include an inner shoulder circumferential groove disposed on an innermost side of the vehicle, and an outer shoulder circumferential groove disposed on an outermost side of the vehicle. Lateral grooves include inner shoulder lateral grooves and outer shoulder lateral grooves. The inner shoulder lateral groove includes a first inner shoulder lateral groove which extends inward in a tire axial direction from an outer side of a vehicle-inner side tread edge and terminates without reaching the inner shoulder circumferential groove, and a second inner shoulder lateral groove which extends inward in the tire axial direction from an outer side of the vehicle-inner side tread edge and opens in the inner shoulder circumferential groove.
