A method for manufacturing a tire wheel having a disc portion mounted to a vehicle and a rim portion for mounting a tire, the method comprising steps of:
- combining a plurality of core pins with a resonance pipe of a ring-shaped hollow pipe;
- preheating the resonance pipe;
- combining the preheated resonance pipe to a mold through the plurality of core pins;
- inserting a molten metal into the mold such that the resonance pipe may be circumferentially formed between the disc portion and the rim portion and formed inside the tire wheel;
- and
- fabricating a plurality of sound absorbing holes that penetrate into the resonance pipe and are equally spaced along a circumference of the rim portion.
