An imbalance in the tire and wheel assembly causes harmonic vibrations. These vibrations occur based on the frequency of the imbalance during rotation. If the imbalance happens once per revolution, it is a first harmonic. If it happens twice, it is a second harmonic. Proper tire balance is essential for maintaining vehicle stability.
Harmonic vibrations result from resonance, where the vehicle’s natural frequency aligns with the vibrations produced by the tires. This alignment amplifies the shaking effect, leading to a more pronounced sensation of vibration throughout the vehicle. If left unaddressed, tire imbalance can cause accruing damage to other parts of the vehicle, such as the steering system and wheel bearings.
It is crucial for vehicle owners to regularly check tire balance. This maintenance can help prevent excess vibration and ensure a smoother driving experience.
In the following section, we will explore additional causes of vehicle shakes. Understanding these causes can lead to effective solutions for improving ride quality and ensuring vehicle safety.
