Why Your Car Might Be Shaking at High Speeds
A car that drives smoothly around town but begins to shake or vibrate once you get on the highway can be frustrating — and sometimes dangerous. Many drivers ask, “Why is my car shaking at high speeds?”, and the causes can range from minor tire issues to more serious suspension or drivetrain problems.
At Round Rock Auto Center, we help drivers track down these vibrations and restore a safe, comfortable ride.
Common Causes of Shaking at Highway Speeds
Shaking that only happens at higher speeds usually points to an issue with the wheels, tires, or suspension. The most common causes include:
Unbalanced wheels – One of the most frequent causes of highway vibration. Even a small imbalance can cause noticeable shaking at 60 mph or more.
Wheel alignment problems – Misalignment can cause uneven tire wear, which often becomes obvious at higher speeds.
Damaged or uneven tires – Flat spots, bulges, or worn tread can cause shaking.
Worn suspension parts – Components like shocks, struts, and bushings help absorb vibration. When worn, you’ll feel it more at high speeds.
Warped brake rotors – Although usually felt during braking, severely warped rotors can sometimes cause vibrations at cruising speed.
Drivetrain issues – Problems with axles, driveshafts, or joints can create noticeable vibrations when accelerating at highway speeds.
How to Narrow Down the Problem
Paying attention to when and how the shaking happens can help point to the cause:
Only at certain speeds? Likely wheel balance.
During acceleration? Could point to drivetrain issues.
Worse on smooth pavement? Tires or suspension may be the cause.
Steering wheel vibration only? Probably a front-end issue.
Why You Shouldn’t Ignore High-Speed Shaking
Driving with your car shaking at highway speeds can:
Make the vehicle harder to control.
Lead to uneven tire wear and early replacement.
Put extra stress on suspension and steering components.
Increase the risk of an accident.
