1. A method for manufacturing a vehicle wheel, the method comprising:
a casting process of forming a one-piece body for the vehicle wheel according to a predetermined shape, the one-piece body having a forming end and a temporary flange protruding at inner and outer sides of the wheel, respectively, at a boundary between a rim and a disc of the wheel, wherein the one-piece body further includes a resonance chamber forming groove defined between the forming end and the temporary flange;
a primary shape machining process of forming a stepped part at an outer circumferential side of the resonance chamber forming groove while machining the temporary flange in a shape for chucking;
a flow forming process of bending the forming end to be seated on the stepped part so that the resonance chamber forming groove defines a closed resonance chamber;
a friction stir welding process of integrally bonding a portion where the forming end and the stepped part are in close contact with each other so that the resonance chamber becomes a closed space;
a fine machining process of removing the temporary flange; and
a sound-absorbing hole machining process of forming a sound-absorbing hole for communication between the resonance chamber and an interior space of a tire in the forming end,
wherein the method, further comprising inserting and fastening a hollow insert neck into the sound-absorbing hole, wherein the hollow insert neck has an inner diameter and a length adjusted according to a target resonance frequency,
during the casting process, a portion to be reduced in weight is formed in a periphery of the sound-absorbing hole.
