TIRE

A tire includes a tread portion including circumferential main grooves extending in a tire circumferential direction; and a belt layer including belt plies. The belt layer includes a circumferential reinforcing layer disposed between a pair of cross belts, having a width in a tire width direction smaller than a width of the cross belts, and having an inclination angle of the belt cords with respect to the tire circumferential direction of 5 degrees or less. The tread portion includes a shoulder portion narrow groove disposed on an outer side in the tire width direction of a circumferential main groove and extending in the tire circumferential direction. A distance WC from a tire equatorial plane to an end portion in the tire width direction of the circumferential reinforcing layer and a distance WN from the tire equatorial plane to the shoulder portion narrow groove satisfy 0.50≤WC/WN≤0.90.
