Pneumatic tire

A pneumatic tire comprising:

• a tread portion extending in a tire circumferential direction and formed into an annular shape;
• a pair of sidewall portions disposed on both sides of the tread portion;
• and
• a pair of bead portions disposed inward of the sidewall portions in a tire radial direction;
• and
• the pneumatic tire having a designated mounting direction on a vehicle;
• the pneumatic tire being provided, in the tread portion, with four main grooves comprising a pair of center main grooves extending in the tire circumferential direction and a pair of shoulder main grooves located outside the center main grooves and extending in the tire circumferential direction,
• the main grooves defining five rows of land portions,
• the center main groove on a vehicle outer side having a zigzag shape in the tire circumferential direction,
• a plurality of lug grooves being provided in the tread portion, the lug grooves extending from the main grooves, except the center main groove having the zigzag shape, toward both sides in a tire lateral direction and terminating in the land portions,
• an inclination direction, with respect to the tire circumferential direction, of lug grooves communicating with the center main groove on a vehicle inner side being opposite to an inclination direction, with respect to the tire circumferential direction, of lug grooves communicating with the shoulder main groove on the vehicle inner side,
• lug grooves extending inward from the shoulder main groove on the vehicle outer side in the tire lateral direction comprising bent portions at terminating ends of the lug grooves, the bent portions being bent toward a first side in the tire circumferential direction,
• a plurality of narrow grooves being formed in the land portion in which the lug grooves comprising the bent portions are formed, the narrow grooves extending discontinuously in the tire circumferential direction without communicating with the bent portions, and
• the narrow grooves being arranged substantially parallel with the center main groove having a zigzag shape.
