PURPOSE: To provide an on-and-off tire maintaining the traction performance on the irregular ground and reducing noises such as impact sound and pattern noises. CONSTITUTION: This on- and-off tire A for a motorcycle is arranged with many blocks on the tread face. A vertical center groove 1 including the tire equator C is formed in the tire peripheral direction on the tread face, and blocks are arranged so that at least one of the right and left blocks 2, 3, 4, 5,... facing each other across the vertical center groove 1 crosses the optional tire width direction line L on the tread face perpendicular to the tire peripheral direction. |
