  • Method of matching wheel and tire
    Patent number: 11656154
    Abstract: A method of matching a wheel and a tire includes 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.
