Abstract: An ATV tire is disclosed which has a plurality of blocks on the tread which extend from one side to another side of said tread in a zig-zag manner form and are spaced apart circumferentially, each of the blocks including a center region C1, middle regions C2, C2, side regions S1, S1 and shoulder regions S2, S2, the center region C1 extending in an axial direction symmetrically about the equator of the tire and having a cut-off portion G therein, the middle regions C2, C2 and the side regions S1, S1 forming a V-shaped bending portion, and the shoulder regions S2, S2 extending axially. The ATV tire is used on the ATV which can run on both rough land and water. When the ATV runs on rough road, the strong traction is attained by such blocks. When running on water, the blocks function as so called of water wheel to blades to attain strong propulsion especially due to the V-shaped bending portion.
