Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the battery to avoid any electrical issues.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to the recommended pressure as stated in the owner’s manual.

3. Tire Inspection and Replacement (if needed)

Remove each wheel using a socket set.
Inspect for damage or uneven wear; replace tires if necessary.
If tires are fine, proceed to the next step.

4. Wheel Balancing

Mount tires on a wheel balancing machine.
Adjust weights on the wheel as needed to achieve balance.
Reinstall wheels and torque to manufacturer specifications (typically around 100-120 lb-ft for Tesla).

5. Wheel Alignment

Use an alignment machine to assess the alignment settings.
Adjust the camber, caster, and toe angles to manufacturer specifications if misaligned.

6. Final Inspection

Recheck all fasteners and components to ensure everything is secure.
Reconnect the battery.
