Abstract: A tire including: a pair of bead cores formed in a polygonal shape in cross-sectional view; a carcass toroidally straddling between the bead cores and folded back around the bead cores; and a wire chafer extending along the carcass so as to cover the carcass folded back around the bead cores from an inner side in a radial direction of a tire, in which, at a side on a tire inner circumference side of the bead core, the wire chafer is provided by being separated into an upper side wire chafer and a lower side wire chafer.

Abstract: A center block of a construction vehicle tire is formed in a range of ?-?, inclusive, of a tread width. A width direction narrow groove is terminated in the center block. A notch groove includes outer grooves formed at each end side of the narrow groove, and inner grooves formed between the outer grooves. A slope portion of the outer groove is inclined to be close to an inner side in the tire radial direction toward one side in the tire circumferential direction. A slope portion of the outer groove is inclined to be close to the inner side in the tire radial direction toward another side in the tire circumferential direction. A slope portion of each inner groove is inclined to be close to the inner side in the tire radial direction toward one side or another in the tire circumferential direction.

Abstract: A tread of a construction vehicle tire includes a first width direction narrow groove and a second width direction narrow groove. Only one notch groove communicated with the first width direction narrow groove is formed in a predetermined range corresponding to a position far away from a tire equatorial line by a distance of ? of a width of the tread. Notch grooves communicated with the second width direction narrow groove are formed in a predetermined range corresponding to a position far away from the tire equatorial line by a distance of 1/16 of the width of the tread and a predetermined range corresponding to a position far away from the tire equatorial line by a distance of ¼ of the width of the tread, respectively.
