The reasons for severe shaking shortly after a car enters the highway are: 1. Uneven brake disc surface with excessive radial runout; 2. Significant deviation in wheel alignment data; 3. Excessive or insufficient tire pressure; 4. Abnormal tire wear; 5. Wheel rim deformation; 6. Shock absorber failure; 7. Tire dynamic imbalance; 8. Engine power failure. The solutions for severe shaking shortly after a car enters the highway are: 1. Inspect and adjust front wheel alignment angles and toe-in; 2. Check wheel dynamic balance; 3. Adjust tire pressure or replace tires; 4. Select high-quality engine oil; 5. Inspect the engine ignition system.
The car started shaking badly shortly after getting on the highway, which is usually related to wheel issues. The most common cause is uneven tire pressure, where one side has more air than the other, leading to imbalance and body vibration at high speeds. Additionally, poor tire balancing or irregular tire wear can also cause this; I experienced it last year when a slightly deformed wheel hub worsened the shaking. Another possibility is aging suspension components, such as failed shock absorbers, which become more noticeable at highway speeds. This situation is quite dangerous, as it can easily lead to tire blowouts or loss of control. Therefore, if you notice this, you should pull over immediately to check tire pressure and wheel condition, then visit a repair shop for balancing or part replacement. Regular maintenance shouldn’t neglect tires—checking pressure and tread depth periodically can prevent trouble. Safe driving is the top priority.
