The tire is further characterized in that, provided that each half portion in the tire width direction of a ground contact surface of the tire is divided in the tire width direction into three equal portions including a tire-width-direction center portion, a tire-width-direction intermediate portion and a tire-width-direction outer portion from the tire-width-direction center side, rigidity in the tire circumferential direction of the belt reinforcing layer in a region in the tire width direction thereof corresponding to the tire-width-direction outer side portion is lower than rigidity in the tire circumferential direction of the belt reinforcing layer in a region in the tire width direction thereof corresponding to the tire-width-direction center portion.",
