What Causes Car Shaking at High Speeds?

[LeTimothy]

The reasons for car shaking at high speeds are as follows: 1. Excessive tire pressure: If the tire pressure is too high, the vehicle will bounce more when driving on bumpy roads, making the car body prone to shaking at high speeds and increasing the risk of a tire blowout. 2. Severe tire wear: If the tires are severely worn with uneven tread surfaces, it can also cause the car body to shake at high speeds. In such cases, the tires should be repaired or replaced promptly. 3. Imbalanced tire dynamic balance: If the wheel balancing weights are displaced or fall off, the tires will lose balance, leading to shaking symptoms when the car is driven at high speeds. In this situation, the balancing weights should be inspected and replaced.
