<p>A tire (22) according to the present invention includes a pair of beads (28), a carcass (30) and a belt (32). An absolute value of an angle formed by a carcass cord of the carcass (30) with respect to a circumferential direction is equal to or greater than 60 degrees and is equal to or smaller than 90 degrees. A belt ply (50) of the belt (32) is constituted by a center portion (52) and a pair of side portions (54) positioned on an outside in an axial direction of the center portion (52). A ratio of a perimeter of the center portion (52) to that of the side portion (54) is equal to or higher than 10% and is equal to or lower than 50%. The center portion (52) includes a center cord which is spirally wound in a substantially circumferential direction and is formed of steel. The side portion (54) includes a side cord which is spirally wound in the substantially circumferential direction and is formed by an aramid fiber.
