- Remove the wheel covers (if equipped) using a flathead screwdriver.
- Loosen the lug nuts using a socket wrench.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel and inspect the tire tread for wear or damage.
- If tires are worn or damaged, replace them with new tires that meet Tesla specifications.
- Reinstall the wheel and lug nuts, tightening to the manufacturer's torque specification (typically around 100 lb-ft for Tesla).

3. Check and Update Software

Sub-steps:
- Connect the vehicle to Wi-Fi.
- Navigate to 'Software' settings in the vehicle display.
- Check for any available updates and follow the prompts to install.
- Ensure the vehicle restarts properly after the update.

4. Traction Control System Reset

Sub-steps:
- Reconnect the 12V battery.
- Power on the vehicle and navigate to the 'Controls' menu.
- Select 'Service', then 'Traction Control', and disable it.
- Wait for 10 seconds, then re-enable the traction control system.

5. Battery and Motor Inspection

Sub-steps:
- Open the front trunk (frunk) and inspect the battery connections for corrosion or loose connections.
- Verify that the motor is securely mounted and that no physical damage is present.
- If any issues are found, consult Tesla service for repairs or replacements.
