Why does my BMW 4 Series shake at high speeds?

I recently noticed that my BMW 4 Series starts shaking when I reach higher speeds on the highway. It seems to smooth out at lower speeds. What could be causing this and how can I fix it?

There could be a few reasons for this shaking. One possible cause could be an unbalanced tire. I recommend taking your car to a trusted mechanic to have the tires balanced if needed.

It's possible that your wheel alignment is off, causing the shaking at high speeds. I suggest getting a wheel alignment done to see if that solves the issue.

Another potential cause could be worn out shock absorbers. If they are old and worn, they may not be able to effectively dampen the vibrations from the road. Consider replacing them if necessary.
