The invention discloses an asymmetrical high vent hole wheel structure which aims at solving the problems that the conventional wheel is poor in heat-dissipation effect, low in structural strength and short in service life. The asymmetrical high vent hole wheel structure comprises a rim and a wheel spoke, wherein the wheel spoke comprises fixed mounting rings, a wheel spoke connecting ring and a plurality of spoke ribs; the spoke ribs are in saddle-shaped structures, and are provided with connecting front sections, connecting middle sections and connecting rear sections from outside to inside in sequentially; the connecting front sections and the connecting rear sections are in arc structures; the connecting middle sections are in planar structures; the spoke ribs comprise base spoke rib parts, sinking spoke rib parts and rising spoke rib parts; altitude differences exist among the base spoke rib parts, the sinking spoke rib parts and the rising spoke rib parts; the connecting middle sections of the sinking spoke rib parts are 0.1-2mm lower than the connecting middle sections of the base spoke rib parts; the connecting middle sections of the rising spoke rib parts are 0.5-2mm higher than the connecting middle sections of the base spoke rib parts; a large vent hole is formed between every two adjacent spoke ribs on the wheel spoke; rounded corners are formed in corner positions where the fixed mounting rings are connected with the spoke ribs in the large vent holes; and the radians of the rounded corners in different positions are different.
