PURPOSE: A method for trial examination of noise of a pneumatic tire is provided to obtain experimental analysis value adjacent to a traveling noise value of a real tire by estimating and analyzing noise of the tire in consideration of phase difference of noise sources and ground pressure. CONSTITUTION: A method for trial examination of noise of the pneumatic tire includes the steps of dividing ground surfaces(t;t1) of a tire of a measuring plate by unit time, taking all ground points(Lt,Tt,Ct;Lt1,Tt1) of the inside of the ground surface as noise source by dividing the ground surface divided by unit time into a vertical direction and a horizontal direction, applying weight values(Aij,Bij,Cij) in consideration of the ground pressure in the corresponding ground points to a sound wave function and integrating, operating noise of the ground surface by unit time, and calculating an experimental analysis value in consideration of a noise occurrence time difference.
