⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when lifting the vehicle for tire repair or replacement to prevent accidents.
•Ensure the tires are cold when checking and adjusting pressure for accurate readings.

Symptoms

•Low tire pressure warning light illuminated on the dashboard
•Visual alert on the vehicle's display indicating specific tires with low pressure
•Possible decrease in handling or ride comfort
•Increased road noise due to under-inflated tires
•Potential loss of fuel efficiency

Diagnostic Steps

1
Check the tire pressure using a calibrated tire pressure gauge for all four tires.
2
Inspect each tire visually for damage, punctures, or signs of wear.
3
Verify the recommended tire pressure settings, typically found on a sticker inside the driver’s door jamb.
4
Check for any recent changes in temperature that may affect tire pressure.
5
Inspect the tire valves for leaks or damage.
6
If equipped, confirm that the Tire Pressure Monitoring System (TPMS) is functioning properly.

Solution

1. Preparation

Tools Required: Tire pressure gauge, air compressor, tire repair kit (if necessary)
Ensure the vehicle is parked on a flat surface and the tires are cold for accurate pressure readings.

2. Inflate Tires

Remove the valve cap from the tire with low pressure.
Attach the air compressor nozzle to the valve stem and inflate the tire to the recommended pressure (usually around 30-35 psi).
Recheck the pressure with the tire gauge to confirm it is within the recommended range.
Replace the valve cap securely.

3. Repair or Replace Damaged Tires

If any tires show signs of punctures or damage, assess if they can be repaired or need replacement.
- For punctures: Use a tire repair kit to seal minor punctures.
- For significant damage: Remove the tire using a jack and tire iron, and replace it with a new tire.
Follow manufacturer guidelines for tire replacement, ensuring you match the specifications for the Tesla Model S.

4. Reset TPMS (if necessary)

After adjusting the tire pressures, navigate to the vehicle's settings on the touchscreen.
Locate the TPMS reset option and select it to recalibrate the system.
