Pneumatic tire

摘要

Abstract Problem: To provide a pneumatic tire whereby steering stability performance and noise performance can be enhanced. Resolution Means: A pneumatic tire IA including at least four circumferential main grooves 21 through 24 extending in the tire circumferential direction and a plurality of rib-like land portions 31 through 35 partitioned by the circumferential main grooves 21 through 24 in the tread portion. Additionally, an outer side second land portion 32 includes a zigzag narrow groove 321 having a zigzag shape, extending in the tire circumferential direction, and dividing the outer side second land portion 32 in the tire width direction; and a plurality of first sipes 322 disposed at a predetermined pitch in the tire circumferential direction, extending from an edge portion on the outer side in the tire width direction of the outer side second land portion 32 toward the inner side in the tire width direction, and terminating prior to the zigzag narrow groove 321, leaving a gap for ventilation.
