A pneumatic tire comprises a tread portion (2) provided with a wavy circumferential groove (7) and a plurality of axial grooves (4). At the junction (5) of each axial groove (4) with the wavy circumferential groove (7), a acute-angled corner (6) is formed. At the junction (5), the axial groove (4) has a toe-side edge (4r) intersecting a junction-side edge (7a) of the wavy circumferential groove (7) at a first point (P1), and a heel-side edge (4f) intersecting the junction-side edge (7a) at a third point (P3). The first point (P1) is positioned between a second intersecting point (P2) and a junction-side maximum amplitude points (RLO) wherein the second intersecting point (P2) is that between the junction-side edge (7a) and a maximally-inclined tangent (Ka) to an opposite-of-junction-side edge (7b) of the wavy circumferential groove (7), and the junction-side maximum amplitude point (RL0) is a point on the junction-side edge (7a) at which the junction-side edge (7a) protrude maximally towards the junction-side. |
