⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is on a flat surface and securely parked before working on tires.
•Allow tires to cool before checking pressure to avoid inaccurate readings.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible fluctuation in vehicle handling or ride comfort
•Decreased fuel efficiency due to under-inflated tires
•Potential audible alerts or visual notifications for low tire pressure
•Loss of traction or stability in adverse weather conditions

Diagnostic Steps

1
Check the tire pressure using a digital or analog tire pressure gauge on all tires, including the spare if applicable.
2
Inspect each tire visually for signs of damage, wear, or punctures.
3
Verify that the tire pressure monitoring system (TPMS) is functioning by checking for any error codes using the Tesla diagnostic tools.
4
Reset the TPMS system via the Tesla infotainment system settings if tire pressures are confirmed to be within the recommended range.
5
Look for any visible damage to the TPMS sensors, which may require removal of the tire to inspect.

Solution

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, portable air compressor, and a tire repair kit if necessary.
Park the Tesla on a flat surface and turn off the ignition to ensure safety.

2. Check and Adjust Tire Pressure

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the current pressure of each tire.
Refer to the owner's manual or the driver's side door jamb for the recommended tire pressure.
If any tire is below the recommended pressure, use a portable air compressor to inflate it to the correct level.
Once all tires are adjusted, replace the valve caps securely.

3. Inspect and Repair Tires

If any tire shows signs of damage or puncture, assess whether it can be repaired or needs replacement.
If repair is necessary, follow these steps:
- Use the tire repair kit to seal small punctures.
- For larger damages, consider replacing the tire entirely.
Ensure that the TPMS sensors are intact during this process.

4. Reset TPMS

Access the Tesla screen and navigate to the settings menu.
Locate the TPMS section and select the option to reset or recalibrate the tire pressure monitoring system.
Confirm the reset and wait for the system to complete the recalibration process.
