3. Replace the valve cap securely after inflating.
Tools Required: Tire pressure gauge, air compressor

3. Inspect and Repair

Sub-steps:
1. If a tire is found to be damaged (punctured or worn), remove the tire from the wheel.
2. Patch or replace the tire as necessary.
3. If the valve stem is damaged, replace it accordingly.
