A method for detecting the imbalanced state of a wheel (10) is disclosed. The method comprises the steps of: utilizing or measuring a tire acceleration signal and generating or extracting tire vertical mode frequency data; determining a wheel hop value from the peak of the curve of the tire vertical mode frequency data; and determining if the wheel hop value is greater than a predetermined threshold value, and then sending an alert if an imbalance is detected. Also, a wheel imbalance detection apparatus for determining if a wheel (10) is out of balance is disclosed. The apparatus comprises: tire vertical mode measuring means for measuring tire vertical mode frequency and generating tire vertical mode frequency data; tire identification means for generating a tire-specific threshold value using tire-specific identification data; and a comparator for comparing the vertical mode frequency data with a threshold value.
