Why is my Ford Focus vibrating at high speeds?

Recently, my Ford Focus has started to vibrate heavily when I reach high speeds on the highway. It almost feels like the whole car is shaking. What could be causing this and how can I fix it?

It's possible that your tires are out of balance or your wheels are misaligned. These issues can cause vibrations at high speeds and can be easily fixed at a tire shop or mechanic.

Check your suspension and steering components for any wear and tear. These parts can also cause vibrations if they are damaged or need to be replaced.

Make sure your lug nuts are tightened properly. Loose lug nuts can cause vibrations and also be a safety hazard.
