A method for simulating a rolling tire and estimating its noise performance is disclosed, wherein a tire model rolling on a rough road surface model is simulated, and coordinates of node points appearing in the outer surface of the rolling tire model are stored as time-series coordinates data. A small gap is formed between a tire outer surface model defined by the time-series coordinates data and a smooth road surface model. Then, a sound field filled with air is defined including the gap, and pressure variations of the air are computed.
