A center block of a construction vehicle tire is formed in a range of ⅛-⅜, 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.
