What Causes Car Shaking at High Speeds?
1 Answers
High-speed car shaking can be attributed to the following reasons: 1. Uneven brake disc surfaces with excessive radial runout. During braking, the inconsistent contact between brake pads and discs causes fluctuating braking force, resulting in body vibration—especially noticeable during light braking. 2. Significant deviation in wheel alignment data. This makes the vehicle harder to control during acceleration, accompanied by slight vibrations. 3. Improper tire pressure (either too high or too low). Overinflated tires intensify shaking at higher speeds, while underinflated tires cause the vehicle to pull to one side. 4. Abnormal tire wear. Irregular tire surface wear due to misaligned wheels or rim deformation leads to body vibration during driving.
