Solution

1. Preparation

Gather necessary tools such as a digital tire pressure gauge and a portable air compressor.
Ensure the vehicle is parked on a level surface and the tires are cold for accurate readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the digital tire pressure gauge to measure the pressure of each tire.
3. Compare the measured pressure with the recommended PSI.
4. If any tire is low, connect the portable air compressor and inflate to the recommended PSI.
5. Recheck the tire pressure with the gauge after inflating.

3. Inspect and Repair Damaged Tires

Sub-steps:
1. Look for punctures or noticeable damage on the sidewalls and tread.
2. If a puncture is found, assess if it can be repaired or if the tire needs replacement.
3. For minor punctures, use a tire repair kit to seal the leak.
4. If the tire is beyond repair, remove it using a socket set and replace it with a new tire.

4. Reset the TPMS

Sub-steps:
1. Access the Tesla touchscreen and navigate to Settings.
2. Select 'Service' and then 'Tire Pressure Monitoring System'.
3. Follow the prompts to reset the TPMS.
4. Ensure the check tire pressure light is no longer illuminated after the reset.
