The invention provides a tubeless radial tire with a full steel wire carcass turn-up and extension feature, and belongs to the technical field of tubeless radial tires. A carcass turn-up end of the tubeless radial tire outwards extends to the outer surface of the tubeless radial tire, is arranged between the edge curve of a rim contour and the horizontal axis of the tubeless radial tire, and is designed in two modes that firstly, the carcass turn-up end exceeds the outer surface of the tubeless radial tire, and no grooves are formed in the outer surface contour of the radial tire; secondly, a smooth groove is designed in the outer contour of the tubeless radial tire, and the carcass turn-up end is arranged in the groove. According to the tubeless radial tire, steel wire wrapping fabric is used for protecting carcass steel wires, a carcass ply turn-up end outwards extends to the outer surface of the tubeless radial tire, and therefore stiffness mutation of a tire bead portion at the carcass turn-up end is avoided, the problem of stress concentration of a rubber material in the tubeless radial tire at the carcass ply turn-up end is solved fundamentally, the problem that the carcass ply turn-up end is damaged is well solved, and the service life of the tubeless radial tire is prolonged by 1.3-1.8 times.
