What Causes Body Vibration in a Car at High Speeds?

[OSimon]

Reasons for body vibration in a car at high speeds: 1. If the tire pressure is too high, the vehicle will bounce more severely on bumpy roads, making the body prone to shaking at high speeds and increasing the risk of a tire blowout. 2. Severe tire wear or uneven tread surfaces can also cause body vibration when driving at high speeds. In such cases, the tires should be repaired or replaced promptly. 3. Imbalanced tire dynamics—if the wheel balancing weights shift or fall off, the tires will lose balance, leading to vibration symptoms during high-speed driving. In this scenario, the vehicle's wheel balance should be checked. 4. Incorrect four-wheel alignment—if the car's four-wheel alignment is not performed after replacing tires, issues such as driving vibration and severe tire wear may occur. In this case, the vehicle should undergo a four-wheel alignment again.
