⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is on a stable surface before lifting it with a jack.
•Wear appropriate safety gear when working with tires and repairs.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Tire pressure readings lower than recommended
•Uneven tire wear may be observed
•Vehicle may exhibit poor handling or traction
•Increased road noise while driving

Diagnostic Steps

1
Check Tire Pressure: Use a tire pressure gauge to measure the air pressure in all four tires, comparing readings with the manufacturer's recommended pressure.
2
Inspect Tires Visually: Look for any visible damage, such as cuts, punctures, or bulges on the sidewalls and tread.
3
Examine Valve Stems: Check each valve stem for leaks or damage that may cause air loss.
4
Reset Tire Pressure Monitoring System (TPMS): Follow the vehicle's manual instructions to reset the TPMS after ensuring all tires are properly inflated.
5
Use Tesla Service Menu: Access the service menu on the touchscreen to view real-time tire pressure data and check for sensor faults.
6
Check for Software Updates: Ensure the vehicle's software is up to date, as updates can affect TPMS functionality.

Solution

1. Preparation

Gather Tools: Obtain a tire pressure gauge, air compressor, and a puncture repair kit if needed.
Safety Measures: Park the vehicle on a level surface, engage the parking brake, and ensure the tires are cold for accurate measurement.

2. Inflate Tires

Sub-steps:
1. Remove the valve cap from each tire.
2. Use the air compressor to inflate each tire to the recommended pressure (typically between 30 to 35 PSI for most vehicles).
3. Recheck the pressure with the tire gauge after inflating to confirm it matches the recommended level.
4. Replace the valve caps securely.

3. Repair or Replace Tires (if needed)

Sub-steps:
1. For minor punctures, clean the area around the puncture and follow the instructions for using a tire repair kit.
2. If the tire is damaged beyond repair, remove it using a jack and lug wrench, replace it with a new tire, and ensure proper torque is applied to the lug nuts (typically 80-100 ft-lbs).
3. If you replace a tire, ensure that the TPMS sensor is installed in the new tire.

4. Reset the TPMS

Sub-steps:
1. Access the touchscreen and navigate to the settings menu.
2. Select the 'Service' menu and follow the prompts to reset the TPMS.
3. Confirm the reset and check if the warning light has turned off.
