What to Do When the Steering Wheel Shakes at 120 km/h on the Highway?

[McEva]

Perform tire balancing. Here is an introduction to steering wheel shaking: Reasons for steering wheel shaking: First, it is due to uneven tire tread causing the steering wheel to shake. Unstable tires will start to vibrate when the car reaches a certain speed, and this vibration will be transmitted upwards through the vehicle's drivetrain, resulting in steering wheel shaking. Second, it is caused by uneven brake disc surfaces leading to vibration. Methods to handle steering wheel shaking: Check if the tire tread is cracked. As tire rubber ages, it becomes hard and cracks, indicating that the tire has reached its replacement limit. The tire's grip decreases, and cracked areas are prone to rupture or blowout due to external impacts while driving. Check if the tread is cut or punctured by nails. After a tire impact, promptly inspect the tread for bulges. Visit a tire repair shop and use a tire balancing machine to perform tire balancing, identifying the unbalanced areas and the required counterweight.
