⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface and the parking brake is engaged before working on tires.
•Allow the tires to cool down before checking or inflating, as heat can affect pressure readings.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible decrease in vehicle handling or stability
•Tire(s) may appear visibly flat or low
•Change in tire noise when driving
•Potential increase in energy consumption while driving

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect tires for visible signs of damage, such as cuts, punctures, or bulges.
3
Verify the TPMS is functioning by checking for any error codes using the Tesla diagnostics tool.
4
Examine the valve stems for leaks or damage.
5
Reset the TPMS through the vehicle's settings if the pressure is corrected.

Solution

Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor, tire patch kit (if needed), and a TPMS reset tool.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Check and Inflate Tires

Remove the valve stem caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Compare the readings to the recommended tire pressure, usually found on the driver’s side door jamb.
If any tire is below the recommended pressure, use the air compressor to inflate it to the appropriate level.
Replace the valve stem caps securely after inflation.

3. Inspect Tires for Damage

Visually inspect each tire for cracks, punctures, or other damage.
If a puncture is found, use the tire patch kit to temporarily seal the hole or take it to a professional for repair.
Check the sidewalls for bulges or other deformities indicating internal damage.

4. TPMS Reset (if necessary)

Navigate to the vehicle settings on the touchscreen.
Find the TPMS reset option in the vehicle settings menu.
Follow the prompts to recalibrate the TPMS after adjusting tire pressures.
Confirm that the warning light is no longer illuminated after the reset.
