  "textContent": "A pneumatic tire is provided for which blocks arranged in a region of the shoulder are unlikely to be damaged, and thus is able to secure running stability on snowy road surfaces. A shoulder block (60) has at least one shoulder sipe (110) having a wavy shape in a tire surface view, and extending in a direction which intersects in a tire-circumferential direction. A central block (70) has at least one central sipe (120) having a wavy shape in a tire surface view, and extending in a direction which intersects in a tire-circumferential direction. An intermediate block (80) has at least one intermediate sipe (130) having a wavy shape in a tire surface view, and extending in a direction which intersects in a tire-circumferential direction. A relationship of Ceθ > Shθ > Meθ is established where ShA is amplitude in a tire surface of the shoulder sipe (110), CeA is amplitude in a tire surface of the central sipe (120), and MeA is amplitude in a tire surface of the intermediate sipe (130).",
