Why Does the Steering Wheel Vibrate at High Speed?
2 Answers
High-speed steering wheel vibration is caused by improper tire dynamic balance, which can be resolved by performing a dynamic balance adjustment. The purpose of dynamic balancing is to ensure that the car tires remain relatively stable when rotating at high speeds, maintaining normal driving conditions. After a car tire is repaired, its mass distribution becomes uneven, so dynamic balance weights need to be added to restore stability. When the dynamic balance of car tires fails, symptoms such as severe bumpiness, abnormal shaking, directional deviation, abnormal steering, and uneven tire wear may occur during driving.
Last time I was driving on the highway, the steering wheel shook violently, and I found out it was due to unbalanced wheels! Tire dynamic imbalance is quite common, especially noticeable at speeds above 80 km/h. This happens because when the wheels rotate at high speeds, any unbalanced points can cause the steering wheel to shake. It's recommended to first visit a tire shop for a check-up and get a dynamic balance correction—it's a simple and inexpensive fix with the right tools. Also, pay attention to whether the tire wear is even; if the sidewalls are heavily worn, that could also lead to imbalance. In short, don't take it lightly—high-speed shaking is unsafe, and addressing it early can prevent bigger car problems.
