PROBLEM TO BE SOLVED: To provide a pneumatic tire that can improve steering stability performance on a dry road surface and steering stability performance on a wet road surface while maintaining or improving noise performance.SOLUTION: A tread pattern of a pneumatic tire comprises: two inner circumferential main grooves; two outer circumferential main grooves; three wave-shape sipes that are provided at regions of inner land parts sectioned by the two inner circumferential main grooves and at regions of intermediate land parts sectioned by each of the inner circumferential main grooves and each of the outer circumferential main grooves; and a closed sipe that is provided at each of the regions of the intermediate land parts, extends in a tire width direction from at least one of the inner circumferential main grooves and the outer circumferential main grooves and terminates without reaching the wave-shape sipes. Groove walls at which the outer circumferential main grooves contact the intermediate land parts and groove walls at which the inner circumferential main grooves contact the intermediate land parts are walls which do not have sipes other than the closed sipes and opening parts of the grooves.SELECTED DRAWING: Figure 2 |
