Solution

1. Preparation

Gather necessary tools and parts.
Ensure you have a reliable tire pressure gauge.
If needed, a portable air compressor may be used for inflating tires.

2. Check and Adjust Tire Pressure

Remove valve caps from all four tires.
Use the tire pressure gauge to measure the pressure of each tire, comparing it to the recommended PSI found in the driver's door jamb.
If any tire is below the recommended PSI, use the air compressor to inflate it to the proper level.
Recheck the pressure after inflation to ensure it is correct.
Replace the valve caps securely.

3. Inspect for Damage

Visually inspect each tire for punctures, cracks, or foreign objects embedded in the tread.
If damage is found, determine if it is repairable or if the tire needs replacement.
For any tire that is beyond repair, remove it using a jack and socket set, and replace with a new tire.

4. Reset TPMS

Navigate to the vehicle settings on the Tesla touchscreen.
Select the option to reset the Tire Pressure Monitoring System.
Confirm the reset and wait for the system to recalibrate.
