What Causes Car Shaking at High Speeds?
3 Answers
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.
I experienced car shaking issues while driving on the highway, often caused by unbalanced tires, such as uneven tire wear or slightly deformed rims, which can make the body shake violently at higher speeds. I remember during a road trip last year, the car started shaking when the speed exceeded 80 km/h. After inspection, it turned out that the dynamic balance of one of the front wheels wasn't properly adjusted, and the mechanic fixed it quickly. It's advisable to regularly check tire pressure and wear. Don't ignore shaking at high speeds as it can easily affect safety. Stop and visit a professional shop promptly to prevent minor issues from becoming major problems.
High-speed car shaking may indicate an issue with the braking system, especially if the brake discs are warped, which can exacerbate the vibration. I once experienced noticeable shaking only when applying the brakes on the highway, but it completely disappeared after replacing the brake discs. This is quite annoying because brake disc warping is usually caused by high temperatures or wear and tear, so it's essential to regularly inspect brake components, such as checking for normal wear. If unusual noises or vibrations are detected, prompt repairs are necessary to avoid safety hazards—safety always comes first.
