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. |
