Abstract

A two-wheeled vehicle tire achieves a further improvement particularly in the traction performance during turning on soft ground. A two-wheeled vehicle tire includes a tread portion formed in an annular shape. The tread portion includes: center land portions arranged on a tire equator CL; middle land portions arranged on the tire width-direction outer side of the center land portions; and shoulder land portions arranged on the tire width-direction outer side of the middle land portions, and T-shaped or Y-shaped land portions each constituted by three partial land portions connected at one end are arranged between the center land portions and the shoulder land portions.

3. The two-wheeled vehicle tire according to claim 2 , comprising a section in which the middle land portions and the T-shaped or Y-shaped land portions are alternately arranged in the tire circumferential direction.

4. The two-wheeled vehicle tire according to claim 1 , comprising a section in which the middle land portions and the T-shaped or Y-shaped land portions are alternately arranged in the tire circumferential direction.

5. The two-wheeled vehicle tire according to claim 1 , wherein the middle land portions and the T-shaped or Y-shaped land portions are alternately arranged along the tire circumferential direction.

6. The two-wheeled vehicle tire according to claim 1 , wherein the middle land portions and the T-shaped or Y-shaped land portions are alternately arranged in the tire circumferential direction, and V-shaped land portions are arranged in place of the T-shaped or Y-shaped land portions in at least one part along the tire circumferential direction.
