Abstract:
      The application of circular wire ring [1×5. 5＋（10＋17＋23）×2. 2] in 12. 00R20 truck and bus tire was studied，and compared with the hexagonal wire ring（7-8-9-10-11-12-11-10-9-8-7）.The results showed that the hexagonal wire ring mainly carried the tensile stress and compressive stress by the central wire，the circular wire ring distributed the tensile stress and compressive stress evenly on each wire，the Mises tensile stress of the hexagonal wire ring was larger，the Mises compressive stress of the hexagonal wire ring was smaller，and the circular wire ring was prone to having the problem of loose strand under compression.The circular wire ring supported bending stress symmetrically，and the Mises bending stress of the hexagonal wire ring was larger.When rotated clockwise，the wire of the circular wire ring tended to straighten，and when rotated counterclockwise，the wire of the circular wire ring tended to tighten.The Mises rotating stress of the hexagonal wire ring was greater than that of the circular wire ring.The tire with the circular wire ring had better durability，and the circular wire ring helped to reduce the tire mass and rolling resistance.
