Diagnostic Steps

1
Inspect each tire for visible punctures, cuts, or damage.
2
Check the valve stems for leaks or damage.
3
Use a tire pressure gauge to measure the current tire pressure against the recommended levels.
4
Inspect the rim for signs of corrosion or damage that may allow air to escape.
5
Submerge the tire in water to check for bubbles that indicate a slow leak.
6
Evaluate the age and condition of the tires; tires older than six years may have degraded rubber.

Solution

1. Preparation

Gather tools and parts for the repair.
Ensure the vehicle is parked on a flat surface and the tires are cool to the touch.

2. Inspect and Repair Tire Damage

Sub-steps:
- Remove the affected tire using a jack and a lug wrench.
- Inspect the tire thoroughly for punctures or damage.
- If a puncture is found, use a tire plug kit to seal it:
  - Clean the puncture site with a reamer.
  - Insert the tire plug according to kit instructions.
  - Trim excess plug material.
- If the damage is severe, consider replacing the tire.

3. Replace Valve Stems

Tools Required: Valve stem tool.
Sub-steps:
- Remove the tire from the rim using a tire machine if necessary.
- Replace the valve stem with a new one.
- Reinstall the tire onto the rim, ensuring proper sealing.

4. Reseal Tires (if applicable)

If the rims are corroded, clean the rim surface thoroughly.
Apply tire sealant to the rim bead and ensure proper installation when remounting the tire.

5. Reinflate Tires

Inflate the tires to the manufacturer's recommended pressure using an air compressor.
Ensure all tires are at the correct pressure.
