What Causes Steering Wheel Vibration at Speeds Over 100 km/h?
2 Answers
Steering wheel vibration at speeds exceeding 100 km/h is caused by: 1. Poor tire dynamic balance: During driving, localized strong impacts may cause the tire's balancing weights to fall off or become damaged, affecting the tire's dynamic balance. 2. Significant differences in four-tire pressure: When there's a substantial difference in tire pressure among the four tires, especially between left and right wheels, the vehicle body will experience noticeable bumps and steering wheel vibration during high-speed driving. Solutions: 1. First, check and optimally adjust the tire pressure, then perform a four-wheel dynamic balance, and finally conduct a four-wheel alignment. This will essentially resolve the steering wheel vibration issue during high-speed driving. 2. If the problem persists, it's recommended to visit a 4S dealership for a thorough inspection of the chassis, braking system, and engine suspension system.
I noticed that when the speed exceeds 100 km/h, the steering wheel shakes, which is mostly caused by unbalanced tires or uneven wear. The last time I drove on the highway, I experienced this—the steering wheel wobbled in my hands. After inspection, I realized the tire balance was off. If the dynamic balance isn't done properly, it can cause shaking at high speeds. Additionally, if tires have been used for a long time and show irregular wear, it can also affect balance. Nowadays, getting a tire dynamic balance test at a repair shop is very convenient and usually costs just a few dozen yuan to fix. If not addressed promptly, it can accelerate tire wear, affect braking distance, and in severe cases, even lead to a tire blowout, which is extremely dangerous. I recommend going to a professional shop for inspection and adjustment as soon as possible to avoid accidents.
