⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is parked safely and away from traffic before performing any checks or repairs.
•Always wear safety gloves when handling tires or tools.

Symptoms

•Warning light for low tire pressure illuminated on the dashboard
•Tire pressure monitoring system (TPMS) alert on the touchscreen
•Uneven tire wear observed on visual inspection
•Decreased handling or stability while driving
•Noticeable decrease in ride comfort or increased road noise

Diagnostic Steps

1
Check the tire pressure of all four tires using a reliable tire pressure gauge.
2
Inspect the tires visually for any visible signs of damage, punctures, or deflation.
3
Verify that the TPMS system is functioning correctly by checking for any faults or error codes using the Tesla service menu.
4
Look for any recent changes in temperature, as colder weather can cause tire pressure to drop.
5
Confirm that the tires are at the manufacturer's recommended pressure specification.

Solution

Solution

1. Preparation

Gather tools: tire pressure gauge, air compressor, and possible replacement valve stems.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the current pressure of each tire.
3. Compare the readings to the recommended pressure listed on the driver’s side door jamb.
4. If any tire is below the recommended pressure, use the air compressor to inflate it to the proper level.
5. Recheck the pressure after inflating to ensure accuracy.
6. Replace valve caps securely after adjusting.

3. Inspect Tires for Damage

Sub-steps:
1. Inspect each tire for visible punctures, cuts, or any foreign objects embedded in the tread.
2. Examine the sidewalls for cracks or bulges.
3. If damage is found, consider replacing the tire or repairing it as necessary.

4. Reset TPMS (if required)

Sub-steps:
1. Navigate to the settings menu on the Tesla touchscreen.
2. Select “Service” and then “Tire Pressure Monitoring System.”
3. Follow the prompts to reset the TPMS if the warning persists after pressure adjustments.
