The invention discloses a variable-angle tire bead of a multiply tire. The variable-angle tire bead comprises bead toes located at the bottom of the tire bead. The bead toes comprise the outer bead toes and the inner bead toes. The inner toe angle of each inner bead toe corresponds to the angle of a steel rim, and the outer toe angle of each outer bead toe is larger than the corresponding inner toe angle. The difference between each outer toe angle and the corresponding inner toe angle is not larger than 5 degrees. The angle of each inner toe angle ranges from 0 degree to 3 degrees. The length of each outer bead toe is equal to that of the corresponding inner bead toe. The variable tire toe angle design is adopted, so that it is guaranteed that the tire bead is tightly matched with the steel rim, and the tire is easy to assemble and disassemble.
