Why does the steering wheel vibrate when driving on the highway?

[DiAndres]

There are many reasons that may cause steering wheel vibration during high-speed driving, such as significant differences in tire pressure among the four tires, poor tire dynamic balance, or inaccurate four-wheel alignment data. Below is relevant information: 1. Precautions: Tires are the only components of a car that come into contact with the ground, making them crucial for driving safety and stability. It is recommended that drivers check tire pressure and inspect the tire surface for any damage before embarking on high-speed or long-distance journeys. 2. Dynamic Balance: If there is an issue with the wheel's dynamic balance, it may also cause the steering wheel to vibrate during high-speed driving. During production, the weight of each part of the wheel rim is not exactly the same, nor is the weight of each part of the tire. After the tire is mounted on the rim, the weight distribution of the wheel is not uniform, necessitating dynamic balancing of the wheel. During dynamic balancing, technicians attach balancing weights to the lighter parts of the wheel to prevent abnormal vibration during high-speed driving.
