Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, TPMS reset tool (if needed).
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure of each tire.
3. Compare the readings with the recommended pressure listed on the driver’s door jamb.
4. If pressure is low, use an air compressor to inflate the tires to the correct pressure.
5. Reattach the valve caps securely.

3. Inspect and Replace Damaged Tires

Sub-steps:
1. Examine each tire for visible damage; if any are found, consider replacing the tire.
2. If punctures are present that can be repaired, use a tire repair kit as necessary.
3. If the tire is beyond repair, remove the tire from the wheel using a tire changing machine.
4. Replace the tire with a new one, ensuring it matches the specifications for the Model 3.
5. Balance the new tire before reinstalling it onto the vehicle.

4. Reset TPMS

Sub-steps:
1. Navigate to the vehicle settings on the touchscreen.
2. Locate the "Tire Pressure" or "TPMS" section.
3. Follow the prompts to reset the tire pressure monitoring system.
4. Confirm that the warning light has turned off.
