<p>The present invention aims to improve the wet performance while securing steering stability and holding down degradations in noise performance to minimum, and for this purpose, a pneumatic tire (1) in which blocks (B) are disposed at intervals at a tread portion thereof is arranged in that concave blocks (B0) with stepped concave portions (10) that extend along block side edges, which face circumferential main grooves (3), and having a depth from a block top surface that corresponds to 20 to 70% of a block height are provided. The concave portions have a length in a tire circumferential direction of 40 to 95% of a length of the block side edges in the tire circumferential direction and a width in a tire axial direction of 2 to 20 mm. <IMAGE></p> |
