The invention provides a semi-steel radial tire blank, which comprises a tire body, a tread and a tire side, wherein the tread is in a rubber strip wrapping structure, namely a single rubber strip is wound on the tire body from the tire side as the starting point along the peripheral direction of the tire body; the adjacent rubber strips are arranged in a clinging manner or a slant stacking manner; the tail end of each single rubber strip is located on the other surface of the tire side, and is finally vulcanized into an overall tire blank body; the width of each rubber strip can be directionally adjusted according to the technological requirements; the width of the new tread is changed by changing the width of each rubber strip; the design structure of a trapezoidal tread made from a traditional single rubber strip and a traditional cutting tread pasting process are changed; the constitutive property and the plasticity of the tire blank are enhanced; the abrasive resistance of the tread of the tire is enhanced; the technological link for manufacturing the tire blank is omitted; the technological zero distance among semi-finished product production procedures is achieved; the production quality of the process is ensured; and the potential quality hazard caused by manual intervention is avoided.
