The invention discloses a weight reduction type wheel arm structure of an asymmetrical high-vent wheel. The arm of the wheel is provided with an axle fixing disc and a rim fixing ring. A wheel fixing disc is connected with the rim fixing ring through spokes. The spokes are integrally in an arched shape in the radial direction of the arm of the wheel, wherein openings of the spokes are inward. Gaps are formed between every two adjacent spokes and the rim fixing ring. Air vents are formed in the spokes of the arched-shaped structure in the tangential direction of the arm of the wheel. Spoke planes are formed in the middles of the spokes. The spoke plane of at least one spokes is inclined in the tangential direction of the arm of the wheel. The spoke plane of at least one spoke is provided with a spoke weight reduction hole. Balance openings are formed in the side, opposite to the spoke weight reduction holes, of the rim fixing ring. By means of the weight reduction type wheel arm structure, the problems that in the prior art, used materials of a wheel rim structure are thick and heavy, and the fuel economy of a whole vehicle is poor are solved effectively. The rim in the weight reduction type wheel arm structure is few in used materials, the wheel is light, the effect is good, the fuel economy of the whole vehicle is good, and very high practical value is achieved.
