A tire (2) for a motorcycle includes a tread (4). The tread (4) has a center region (18), a pair of shoulder regions (20) and a pair of middle regions (22). In straight running, the center region (18) mainly comes in contact with a road surface. In cornering, the shoulder region (20) mainly comes in contact with a road surface. A modulus (Mm) of a rubber composition in the middle regions (22) is lower than a modulus (Mc) in the center region (18) and is higher than a modulus (Ms) in the shoulder regions (20). A ratio ((Mc−Mm)/(Mm−Ms)) is equal to or higher than 1/3 and is equal to or lower than 3/1. A ratio (Wm/W) is equal to or higher than 0.3 and is equal to or lower than 0.8. A ratio (Wc/W) is equal to or higher than 0.1 and is equal to or lower than 0.4. A ratio (Ws/W) is equal to or higher than 0.1 and is equal to or lower than 0.4.
