A tire of the present disclosure includes a carcass extending toroidally between a pair of bead portions, a belt layer on the tire radial outer side of a crown portion of the carcass, and a belt reinforcement layer on the tire radial outer side of the belt layer. The tire includes an organic fiber cord coated with an adhesive composition including polyphenols and aldehydes, and when a tire widthwise region centered on the tire equatorial plane and having a width in the tire width direction of 2/3 of the length between the ground contact edges is a center region, and tire widthwise regions between the ground contact edges and tire widthwise outer sides of the center region are shoulder regions, the tensile elastic modulus of the belt reinforcement layer in the center region is smaller than the tensile elastic modulus of the belt reinforcement layer in the shoulder regions.
