The invention provides a bead structure of a tire, the tire, a wheel with an inner tube and a wheel without an inner tube. The bead structure comprises a steel wire ring and a bead body, the bead ring is arranged in the bead body, the bead body comprises a bead toe bottom surface, the axial inner side of the bead toe bottom surface comprises a bead toe tip, the axial outer side of the bead toe bottom surface forms a supporting surface, and the radial lowest point, close to the axial inner side, of the bead ring is perpendicular to the supporting surface to form a perpendicular point. A connecting surface is connected between the foot point and the bead toe tip, the radial size of the connecting surface is larger than that of the foot point, and the radial point of the bead toe tip is higher than that of the foot point. By reducing the size of bead toes and optimizing the size of the inner diameter, the matching degree of the inner diameter of the tire and the size of the outer edge of a rim is improved, the radial deformation required by the bead during assembly is reduced, the mounting resistance is greatly reduced, and the operation efficiency is improved.

    本发明提供了一种轮胎的胎唇结构、轮胎、有内胎的车轮和无内胎的车轮,所述胎唇结构包括钢丝圈和胎唇本体;所述钢丝圈设置在所述胎唇本体内,所述胎唇本体包括胎唇趾底面,所述胎唇趾底面的轴向内侧包括胎唇趾尖,所述胎唇趾底面的轴向外侧形成一支撑面,所述钢丝圈靠近轴向内侧的径向最低点垂足于所述支撑面以形成一垂足点,所述垂足点和胎唇趾尖之间连接有一连接面,所述连接面的径向尺寸大于所述垂足点,所述胎唇趾尖的径点高于所述垂足点。通过削减胎唇趾体积并优化内径尺寸,使轮胎内径与轮辋外缘的尺寸匹配度提高,装配时胎唇所需径向变形量减少,大幅降低安装阻力,操作效率提升。
