A tube-shaped tubeless tire includes a tire body having two sidewalls and an inner surface, each of the two sidewalls being externally provided along a radially inner edge with an annular recess; a lining belt having two outer edges separately connected to the inner surface of the tire body, making the tire body a closed tube-shaped body; and a wheel rim being provided along two opposite annular outer edges with a laterally inward protruded annular rib each to face toward the annular recess on the sidewalls of the tire body. When pumping air into the tire body, the tire body and the lining belt are gradually expanded to push the annular recesses on the tire body against the annular ribs on the wheel rim, so that the tire body is completely held to the wheel rim.
