⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked safely before inspecting tires.
•Allow tires to cool before measuring pressure for accurate readings.

Symptoms

•Low tire pressure warning message on the dashboard
•Tire pressure readings in the vehicle's display showing low values
•Potential uneven tire wear due to incorrect pressure
•Vehicle handling issues, such as pulling to one side
•Reduced fuel efficiency or range

Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect each tire for visible signs of damage, such as punctures or sidewall bulges.
3
Verify the functionality of the TPMS by checking for any fault codes using a diagnostic scanner.
4
Inspect the TPMS sensors for corrosion or damage, particularly if the vehicle has experienced tire changes recently.
5
Reset the TPMS through the vehicle's settings if no faults are found.

Solution

1. Prepare for Inspection

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

2. Check and Inflate Tires

Sub-step 1: Use a tire pressure gauge to measure the pressure in each tire, including the spare if applicable.
Sub-step 2: Compare the measured pressures with the recommended tire pressures found on the driver's door jamb.
Sub-step 3: If any tire is below the recommended pressure, use an air compressor to inflate it to the correct level.
Sub-step 4: Re-check the tire pressure after inflating.

3. Inspect Tires for Damage

Sub-step 1: Visually inspect each tire for punctures, cracks, or any other damage.
Sub-step 2: If damage is found, repair it using a tire repair kit or consult a professional for replacement.

4. Reset TPMS (if necessary)

Sub-step 1: Navigate to the TPMS reset option in the Tesla's settings menu.
Sub-step 2: Follow the on-screen instructions to reset the TPMS.
Sub-step 3: Confirm that the warning message has cleared from the display.
