Tubeless radial truck tire

The utility model belongs to the technical field of tire manufacturing, and particularly relates to a tubeless radial truck tire. An original tubeless product matched with the 5-degree flat-bottom rimfor use is innovatively designed into a tubeless product, reasonable interference of matching of the 5-degree flat-bottom rim and a tubeless tire bead is determined, tubeless of the 5-degree flat-bottom rim is achieved, and meanwhile the problems that the tubeless tire is poor in load capacity, weak in tire bead supporting capacity and poor in tire bead supporting capacity are solved. And the service performance of the tubeless tire under severe road conditions is influenced. The utility model breaks through the traditional design concept, breaks through innovation on the contour and structural design of the tire, and innovatively designs the rim, the seam allowance part and the tire toe part through the innovative contour and the innovative structure, so that the seam allowance supporting performance is excellen
