Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, and valve stem tool (if needed).
Park the vehicle on a flat surface and engage the parking brake.

2. Inflate Tires

Sub-steps:
1. Remove the valve stem caps from each tire.
2. Use the tire pressure gauge to measure the current tire pressure.
3. Compare the readings to the recommended pressure listed in the owner's manual.
4. If the pressure is low, use an air compressor to inflate the tire to the recommended level.
5. Recheck the pressure after inflation to ensure it meets specifications.
6. Replace the valve stem caps securely.

3. Inspect for Damage

Sub-steps:
1. Visually inspect each tire for punctures, cracks, or sidewall damage.
2. If a puncture is found, determine if it can be repaired or if the tire needs replacement.
3. Check the valve stem for leaks or damage. Replace if necessary.

4. Reset TPMS (if applicable)

Sub-steps:
1. Turn on the Tesla's ignition without starting the engine.
2. Navigate to the "Service" menu on the touchscreen.
3. Select "Tire Pressure Monitor" and then choose the option to reset or recalibrate the system.
4. Drive the vehicle for a few minutes to allow the system to update.
