1. A method of matching a wheel and a tire, comprising the steps of:
measuring inner runout and outer runout of a wheel;
extracting and setting a primary component of a measurement waveform of the inner runout as an inner runout waveform and extracting and setting a primary component of a measurement waveform of the outer runout as an outer runout waveform;
comparing an inner minimum value that is a minimum value of the inner runout waveform and an outer minimum value that is the minimum value of the outer runout waveform with a predetermined runout reference value; and
determining an assembly reference position of the wheel based on the inner minimum value or the outer minimum value or based on a resultant waveform of the inner runout waveform and the outer runout waveform, depending on a result of the comparing step;
wherein in a wheel and tire assembly formed by combining the wheel and the tire, the assembly reference position of the wheel is matched with a position of a maximum radial force variation of the tire; and
wherein when both of the inner minimum value and the outer minimum value are greater than or equal to the runout reference value, the assembly reference position of the wheel is determined as a position of the minimum value of the resultant waveform of the inner runout waveform and the outer runout waveform.
