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

[DallasRose]

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 130 km/h. Tire Dynamic Imbalance: If a tire experiences a strong localized impact 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 significant 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 a large deviation angle, the car may exhibit phenomena such as body drift and vibration during high-speed driving. It can also lead to uneven tire wear, accelerating tire wear and shortening the tire's service life. Solutions for Steering Wheel Vibration at Speeds Above 130 km/h: When the car experiences steering wheel vibration at high speeds, the first step is to check and adjust the tire pressure. Then, perform a dynamic balance check on all four tires, and finally, conduct a four-wheel alignment.
