Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, soapy water solution.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check Tire Pressure

Use the tire pressure gauge to measure the air pressure in each tire.
- Refer to the manufacturer’s recommended tire pressure (usually found on a sticker inside the driver’s door jamb).
If pressure is below recommended levels, proceed to inflate the tires.

3. Inflate Tires

Using an air compressor, add air to tires that are underinflated.
- Inflate each tire to the recommended pressure, checking periodically with the gauge.
Replace the valve caps securely after inflating.

4. Inspect for Damage

Visually examine each tire for any signs of puncture, cracks, or foreign objects lodged in the tread.
If any damage is found, the tire may need to be repaired or replaced.

5. Reset TPMS

Access the Tesla's display, navigate to the settings menu, and select the TPMS reset option.
Confirm the reset and monitor if the warning light turns off after driving for a short distance.
