Abstract:
A pneumatic tire including a white rubber part arranged outward in a tire radial direction than an outer edge of a bead filler in a side wall part, a white letter part projecting from the white rubber part, and a side reinforcement layer extending in a tire radial direction from a bead part is disclosed. An outer peripheral edge of the side reinforcement layer is located outward in a tire radial direction than an inner peripheral edge of a white letter part. When a length in a tire radial direction of from an inner peripheral edge of a bead core to the inner peripheral edge of the white letter part is H1, a length in a tire radial direction of from the inner peripheral edge of the bead core to the outer peripheral edge of the side reinforcement layer is H2, and a length in a tire radial direction of the white letter part is T, (H2−H1)/T is set to be 0.3 or more.
