PROBLEM TO BE SOLVED: To provide a method for modelling a tire for use in a simulator coupled to a vehicle spindle whereby a tire load can be correctly estimated through a computer simulation without requiring a vast amount of calculations by a computer, and which can be easily executed by a simulation control apparatus coupled to a spindle with the use of an effective road face characteristic. SOLUTION: According to this method, a flat road face is determined by a coordinate system including three coordinates of a displacement in a vertical direction of a plane, a contact angle in a radial direction of the plane and a contact angle in a lateral direction of the plane so as to express an effective road face characteristic 96. The effective road face characteristic 96 is obtained by generalizing an opposite tire model 104 of a tire to be unrelated to a vehicle B from dynamic data obtained when the vehicle B runs. A test tire is mounted to a test stage and oscillated in a preliminarily set range related to each of the three coordinates. A tire model is constituted with the use of an apparatus identification technique on the basis of oscillation input data and response output data.
