Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
If applicable, disconnect the battery before working on electrical components.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove wheel covers or hubcaps if present.
- Check for any visible damage such as cuts or bulges.
- Measure tread depth across the width of each tire.
Replace Tires if Needed:
- If any tire is worn beyond the recommended tread depth, replace it with a new tire of the same specifications.

3. Tire Balancing

Remove Tires:
- Use a socket set to remove lug nuts and take off the tires.
Balance Tires:
- Mount the tires on a tire balancing machine.
- Add weights as necessary to balance each tire according to machine readings.

4. Suspension Inspection and Adjustment

Inspect Suspension:
- Visually check control arms, bushings, and shock absorbers for signs of wear.
- Use a pry bar to check for play in the bushings.
Replace Worn Components:
- If any components are found to be damaged, replace them with OEM or equivalent parts.

5. Reassemble and Torque

Reinstall Tires:
- Place the balanced tires back onto the wheel hubs.
- Hand-tighten lug nuts initially, then use a torque wrench to tighten to manufacturer specifications (typically 80-100 ft-lbs for BMW).

6. Final Checks

Test Drive:
- Drive the vehicle at various speeds to ensure the vibrations are resolved.
- Monitor the steering and handling for any irregularities.
