The invention discloses an asymmetric spoke with highly-ventilated air holes for the purpose of solving defects of a conventional automobile spoke such as loud noise, poor overall strength of the spoke and short service lifetime when an automobile is driven at high speed. The asymmetric spoke comprises a fixed installation ring, a spoke connecting ring and multiple strips of spokes connected between the fixed installation ring and the spoke connecting ring. The spokes are of saddle-shaped structures. From one end to the other end, each spoke sequentially comprises a front connecting segment, a middle connecting segment and a back connecting segment. Each front connecting segment and each back connecting segment are of arc structures. Each middle connecting segment is of a planar structure. Radial sections of middle connecting segments of any two to three spokes are upwardly arranged from the inside to the outside or titled downwards. Inclination angles of 0 to 5 degrees are formed among the radial sections of the middle connecting segments of any two to three spokes and the horizontal plane. The transverse sections of middle connecting segments of any two to three spokes are arranged in an upward or downward titling manner along the clockwise direction. Inclination angles of 0 to 8 degrees are formed among the transverse sections and the horizontal plane. A large vent hole is arranged between two adjacent spokes of the spoke.
