The invention discloses an air hole structure of an asymmetric wheel having a highly-ventilated air hole. An air hole is arranged in a wheel spoke of a wheel. One spoke of the wheel spoke is formed in such a manner that an upper-segment spoke, a middle-segment spoke and a lower-segment spoke connected with a fixing ring of a rim are sequentially connected. Each upper-segment spoke and each lower-segment spoke are of arched shapes. Each overall spoke is of an arched structure having an inward opening in a radial direction of the wheel spoke. A gap is formed between two adjacent spokes and a gap is formed between fixing rings of rims. An air hole is formed in each spoke having an arched structure in the tangential direction of the wheel spoke. At least two spokes are integrally inclined in the tangential direction of the wheel spoke. An included angle of 3 to 8 degrees is formed between the central axis of an air hole inside each spoke and a radial plane of the wheel spoke. The air hole structure of the asymmetric wheel having the highly-ventilated air hole has following beneficial effects: problems of a conventional spoke structure of the wheel including thick materials, great weight and poor heat radiation and fuel economy performance of a complete vehicle are solved; and the wheel spoke is advantaged by being few in material, fine in heat radiation effect and fuel economy performance of the complete vehicle so that high practical value is obtained.
