What Causes Tire Vibration?
2 Answers
Tire vibration causes introduction: Excessive or insufficient tire pressure: Once the vehicle speed is relatively high, the body vibration amplitude increases, and the tires will also vibrate accordingly. Abnormal tire wear. Due to wheel alignment or rim deformation, the tire surface wears unevenly, causing body vibration during driving. Uneven brake disc surface: During braking, the contact between the brake pads and the brake disc is discontinuous, resulting in fluctuating braking force, which can also cause tire vibration. Large deviations in the four-wheel alignment data of the wheel tires, such as issues with the front wheel alignment angle data, can lead to wheel hub deformation and abnormal wear, causing tire dynamic balance failure and resulting in certain vibrations during driving. Damaged shock absorbers: If the shock absorbers lose their effectiveness, the impact of the road on the tires will be more significant, leading to greater tire vibration. Half-shaft resonance. This situation is usually caused by a bent half-shaft (in front-wheel-drive vehicles) or drive shaft (in rear-wheel-drive vehicles).
I've encountered tire shaking several times, and it's quite common. There are usually several reasons: first is wheel imbalance, where the wheel still wobbles after adding balancing weights, especially noticeable at high speeds. Second is issues with the tire itself, such as uneven wear or uneven tread, causing rotational imbalance. Wheel rim deformation is another factor; sometimes hitting potholes or curbs can bend it, so you need to carefully check if the rim is normal. Loose or damaged bearings can also cause shaking, indicated by a humming noise. Additionally, incorrect tire pressure (too high or too low), uneven brake rotors, or aging suspension systems can lead to shaking. My experience is, don't underestimate this shaking—it could lead to accidents if ignored at high speeds. So, when you notice shaking, slow down and stop, then visit a professional shop for a dynamic balance check or wheel alignment to stay safe.
