The invention provides an all-steel wire tubeless radial tire with an external steel wire chafer end, and belongs to the technical field of tubeless radial tires. The technical prejudice of the art is overcome, and a steel wire chafer turnup end is boldly extended to the outer surface of the tire between a rim contour edge curve and a horizontal axis position of the tire. The end design comprises two modes: 1. the steel wire chafer turnup end protrudes out of the outer surface of the tire, and the contour of the outer surface of the tire is grooveless; 2. a smooth groove is designed in the outer contour of the tire, and the steel wire chafer turnup end is arranged in the groove. A tire body steel wire is protected by the steel wire chafer, and the steel wire chafer turnup end is extended to the outer surface of the tire, so that the stiffness mutation of a tire bead part at the steel wire chafer turnup end part is avoided, and thus the problem of stress concentration of a rubber material in the tire on the steel wire chafer turnup end is fundamentally solved, the damage problem of the steel wire chafer turnup end is solved, and the service life of the tire is prolonged.
