Abstract
A tire used for the motorcycle tire and tire set includes: a crossing groove and a non-crossing groove. A groove group of the crossing groove and the non-crossing groove is repeatedly provided in tire circumferential direction so that adjacent groove groups are symmetric with respect to a tire equatorial plane. First, second, and fifth groove portions extend toward one side in tire circumferential direction and third and fourth groove portions extend toward the other side in tire circumferential direction. A first bend portion is located in a shoulder region nearer the one tread edge, a second bend portion is located in a middle region nearer the one tread edge, and a third bend portion is located in a middle region nearer the other tread edge. Inclination angles of the second, fourth and fifth groove portions are each larger than an inclination angle of the first groove portion.
