Solution

1. Preparation

Gather tools and materials: tire pressure gauge, soapy water solution, valve core tool, tire repair kit, tire sealant (if needed), and jack.
Ensure the vehicle is parked on a flat surface and that the parking brake is engaged.

2. Inspect and Repair

Visual Inspection:
- Examine each tire for punctures or sidewall damage.
- Look for uneven wear patterns that may indicate alignment issues.
Leak Detection:
- Apply the soapy water solution to the tire surface and valve stems.
- Observe for bubbles forming, indicating a leak.
Valve Stem Replacement:
- If leaks are found at the valve stems, remove the valve cap and use the valve core tool to replace the valve core.
- Recheck the tire pressure after replacing the valve core.

3. Tire Repair or Replacement

Repair Punctures:
- For small punctures, use a tire repair kit to insert a plug.
- Ensure the area around the puncture is clean and dry before applying the plug.
Replace Damaged Tires:
- If any tire is severely damaged, remove the tire using a jack and appropriate tools.
- Replace the damaged tire with a new one, ensuring proper mounting and balancing.

4. Re-inflate Tires

Inflate each tire to the manufacturer’s recommended pressure, typically found on the driver’s side door jamb.
Recheck each tire with the tire pressure gauge.
