1. A method for non-destructive analysis of natural vibrations of a tire comprising the steps:

  • fitting a tire to be analysed on a wheel;

    arranging said wheel in an apparatus comprising a wheel support supporting said wheel, wherein said wheel support is adjustably fastened to a stiff frame flexibly connected to a base part by elastic means such that separate analysis of the natural vibrations in a predefined functional direction is allowed;

    excitation of vibrations in the predefined functional direction in said wheel by means of an actuator;

    measuring an input signal at a contact surface between said tire and said wheel;

    measuring an output signal at a surface of said tire; and

    calculating transfer function of said tire by means of the input signal and the output signal.
