Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves during the procedure.

2. Tire Inspection

Remove all four tires from the vehicle using a jack and jack stands.
Inspect each tire for signs of uneven wear.
- Replace tires if tread depth is below the minimum specification (2/32 inches).
Document findings for future reference.

3. Wheel Alignment

Set up the wheel alignment machine according to the manufacturer's specifications.
Adjust the front and rear alignment angles to match factory settings.
- Camber: typically between -0.5 to 0.5 degrees
- Toe: typically between 0 to 1/16 inch
Tighten all adjustment bolts to the specified torque (usually around 50-70 ft-lbs).

4. Suspension Inspection

Examine all suspension components for any signs of wear or damage.
Replace worn bushings, struts, or other components as necessary.
Ensure all bolts are torqued to specifications.

5. Tire Replacement (if applicable)

If tires are worn beyond safe limits, install new tires.
Ensure the new tires match the manufacturer's specifications for size and type.
Inflate tires to the recommended PSI (usually around 42 PSI for Model S).
