Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always allow tires to cool before checking or adjusting pressure, as heat from driving can give inaccurate readings.

Symptoms

•Low tire pressure warning light on the dashboard
•Possible decrease in handling and stability while driving
•Tire pressure readings below the recommended levels on the touchscreen
•Rough ride quality or increased road noise
•Visual inspection may show deflated appearance in one or more tires

Diagnostic Steps

1
Check the tire pressure using a reliable tire pressure gauge.
2
Inspect each tire for visible damage, punctures, or irregular wear.
3
Verify the recommended tire pressure by checking the vehicle's door placard or owner's manual.
4
Monitor for any apparent leaks by applying soapy water around the valve stems and tire bead areas.
5
Use the Tesla app or touchscreen to check for any stored error messages related to the tire pressure monitoring system (TPMS).

Solution

💡 Expert Tip

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, soapy water solution, and a valve stem tool.
Ensure the vehicle is parked on a level surface.

2. Inflate Tires

Sub-step 1: Use the tire pressure gauge to check the pressure of each tire.
Sub-step 2: Compare the readings to the recommended pressure.
Sub-step 3: If any tire is below the recommended level, use an air compressor to inflate it to the correct pressure (usually around 30-35 PSI for most passenger vehicles).
Tools Required: Tire pressure gauge, air compressor.

3. Inspect for Damage

Sub-step 1: Visually inspect each tire for cuts, punctures, or signs of wear.
Sub-step 2: If a puncture is found, consider using a tire repair kit or consult a professional for a proper patch or replacement.
Tools Required: Tire repair kit (if necessary).

4. Reset TPMS

Sub-step 1: After adjusting the tire pressure, go to the Tesla touchscreen.
Sub-step 2: Navigate to the "Vehicle" menu and select "Service."
Sub-step 3: Choose "Reset Tire Pressure Monitoring System" to clear the warning light.

5. Final Check

Sub-step 1: Recheck the tire pressures after driving a few miles to ensure they remain stable.
Sub-step 2: If the warning persists after correcting tire pressures, further diagnostics may be necessary to check the TPMS sensors.
