Why Does the Steering Wheel Shake When Driving at 100 km/h?
2 Answers
Steering wheel shaking at 100 km/h is usually caused by unbalanced car tires, and it is recommended to perform wheel balancing. Here are some additional details: 1. A car wheel is an assembly consisting of a tire and a rim. However, due to manufacturing factors, the mass distribution of this assembly is not uniform, leading to an unbalanced wheel. 2. It is recommended that car owners regularly check wheel balancing, which not only extends the life of the tires but also improves driving stability. 3. To maintain the steering wheel properly, it is important to lubricate it regularly, avoid turning the steering wheel to its extreme limits, and periodically inspect the tie rods. 4. If the steering wheel is difficult to control, or if the vehicle tends to pull to one side during driving or braking, this may be due to inconsistent specifications or tire pressure between the two front wheels. Unequal front wheel camber, inconsistent front wheel bearing clearance, or excessive wheelbase differences can also cause this issue.
When the steering wheel shakes at a speed of 100 km/h, it's mainly due to tire balance issues. During high-speed driving, uneven tire wear or slight wheel hub deformation can cause vibrations that are felt as shaking in the steering wheel. This is usually the result of wheels not being dynamically balanced—just like when a wheel spins fast, even a small imbalance can be amplified. If not addressed promptly, the shaking may damage the suspension or steering system, increase fuel consumption, or even risk a tire blowout. I've experienced it myself—I had to slow down every time I hit the highway for fear of problems. The best solution is to have a professional shop check the tire balance and inspect the wheel hubs and suspension for any damage. Developing a habit of regular maintenance, checking tire pressure before every tire change or long trip, can help prevent such issues in advance.
