What Causes Steering Wheel Vibration at Speeds Above 130km/h?

[VonAnnie]

Tire dynamic imbalance, significant differences in tire pressure among the four tires, and poor four-wheel alignment can cause steering wheel vibration at speeds above 130km/h. Tire Dynamic Imbalance: If a tire experiences a strong impact in a localized area during driving, it can cause the balance weights to fall off or become damaged, thereby affecting the tire's dynamic balance. Significant Differences in Tire Pressure Among the Four Tires: When there is a large difference in tire pressure among the four tires, especially between the left and right wheels, the car will experience noticeable body jolts and steering wheel vibration during high-speed driving. Poor Four-Wheel Alignment: When the four-wheel alignment has significant deviation angles, the car may exhibit body drift and vibration during high-speed driving. This can also lead to uneven tire wear, accelerating tire wear and shortening the tire's lifespan. Solutions for Steering Wheel Vibration at Speeds Above 130km/h: When steering wheel vibration occurs at high speeds, the first step is to check and adjust the tire pressure. Next, perform a dynamic balance check on all four wheels, and finally, conduct a four-wheel alignment.
