What causes the vehicle's wheel to shake at high speeds?

I've been experiencing some vibration in the steering wheel of my BMW X3 when driving at high speeds. What could be causing this and how can I address it?

The most likely cause of this issue is an unbalanced or damaged wheel. It is important to get this addressed as soon as possible as it can lead to other problems in the long run.

Another possible cause could be worn out suspension components. It is important to get the suspension checked and replaced if necessary to prevent further damage to the vehicle.

Make sure to also check the tires for any bulges or uneven wear, as this can also cause vibrations at high speeds. Consider getting a wheel alignment if necessary.
