  "textContent": "A pneumatic tire having wavy-shaped sipes is provided with improved traction and durability. A tire includes a tread (10). The tread (10) includes blocks (13) having sipes (14) extending in a direction which intersects a tire-circumferential direction. The sipe (14) has a wavy shape in an extending direction of the sipe (14). The sipe (14) has an opening at a surface of the block (13) and a bottom. The wavy shape continues from the opening to the bottom. Amplitude of the sipe (14) is greatest at the opening and smallest at the bottom. The amplitude decreases at a fixed rate of change from the opening to the bottom, whereby the sipe (14) is linear from the opening to the bottom in a cross-sectional view in the depth direction which is substantially orthogonal to the extending direction of the sipe (14).",
