Solution

1. Preparation

Tools Required: Tire pressure gauge, soapy water solution, tire repair kit (if applicable), floor jack, jack stands.
Park the vehicle on a level surface and engage the parking brake.
Remove any hubcaps or wheel covers if necessary to access the valve stems.

2. Identifying the Leak

Sub-steps:
- Use the tire pressure gauge to confirm which tire(s) are low on air.
- Apply the soapy water solution to the surface of the tire, including the sidewalls and valve stem.
- Observe for bubbles forming, which indicate the location of the leak.

3. Repairing the Leak

Sub-steps:
- If a puncture is found, follow the instructions of the tire repair kit:
  - Remove the object (if applicable).
  - Ream the hole using the reaming tool from the kit.
  - Insert the plug into the hole using the insertion tool, ensuring a tight seal.
  - Trim excess plug material if necessary.
- If the leak is at the valve stem, replace the valve stem:
  - Remove the tire from the rim using a tire removal tool.
  - Replace the valve stem with a new one and reassemble the tire.

4. Reinstallation and Inflation

Sub-steps:
- Place the tire back on the rim and ensure it is seated properly.
- Inflate the tire to the manufacturer’s recommended pressure using an air compressor.
- Reinstall the tire on the vehicle and torque the lug nuts to the specified value (typically 80-100 ft-lbs depending on model).
