<p>Provided is a pneumatic tire that has increased wet performance without sacrificing steering stability and wear resistance. A middle land (12) is provided with a middle sipe (15) and a middle sub-groove (16). The middle sipe (15) has an arc shape such that the angle (θ1) with respect to the tire peripheral direction from the inner end (15i) towards the outer end (15o) gradually increases, and the length (L2) in the tire peripheral direction is 0.6-1.0 times the installation pitch (P2) of the middle sipe (15). The middle sub-groove (16) interconnects with a shoulder primary groove (10), ends without interconnecting with a crown primary groove (9), and has an arc shape having an angle (θ2) that gradually increases from the inner end (16i) to the outer end (16o). The length (L3) of the middle sub-groove (16) is less than the length (L2) of the middle sipe, and an adjacent middle sipe (15) and middle sub-groove (16) are overlapping each other in the tire axial direction.</p> |
