Solution

1. Preparation

Gather tools and equipment: Tire pressure gauge, jack, jack stands, torque wrench, and diagnostic tool.
Ensure the vehicle is parked on a level surface and the battery is charged.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable.
2. Loosen the lug nuts with a wrench.
3. Use a jack to lift the vehicle and secure it with jack stands.
4. Remove the wheels and inspect tires for damage, wear, and proper tread depth.
5. Replace tires if they are worn beyond the tread indicators (usually below 2/32 of an inch).
6. Reinstall wheels and tighten lug nuts to manufacturer specifications (typically 129 lb-ft for Model S).

3. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure.
2. Inflate or deflate each tire to match the recommended pressure found on the driver's side door jamb.
3. Ensure the spare tire (if equipped) is also checked.

4. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components including control arms, bushings, and struts for signs of wear or damage.
2. Test the suspension by pushing down on each corner of the vehicle to ensure it rebounds correctly.
3. Replace any worn suspension parts as necessary.

5. Software Update

Sub-steps:
1. Connect the vehicle to Wi-Fi.
2. Access the software update screen on the touchscreen.
3. Download and install any available updates.
