What is the most common frequency range for vibrations caused by wheel-tire imbalance?

The most common frequency range for vibrations caused by wheel-tire imbalance is 5-20 Hz. This range is significant because it corresponds to the rotational frequencies that are typically generated by the wheels as they spin. When a tire has an imbalance, whether due to uneven weight distribution or a defect, it causes the wheel to vibrate. These vibrations manifest primarily at lower frequencies, particularly when the vehicle travels at moderate speeds, typically around 40-60 miles per hour.

Understanding the frequency range is critical for diagnosing and addressing issues related to wheel-tire imbalance, as vibrations in this range can lead to noticeable discomfort and handling problems in the vehicle. It can also cause premature wear on suspension components and tires if not appropriately addressed. Recognizing this frequency range is an essential aspect of vehicle maintenance for optimal ride quality and safety.
