Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles during the repair.

2. Tire Inspection

Sub-steps:
1. Remove the tire from the vehicle using a jack and wrench.
2. Visually inspect the entire tire surface for nails, screws, or cuts.
3. Check the valve stem for cracks or leaks; replace if necessary.

3. Repair or Replace Tire

Sub-steps:
1. If a puncture is found, consider using a tire plug kit for small punctures or take the tire to a professional for a patch.
2. If the tire is damaged beyond repair, replace it with a new tire that matches the specifications of the other tires.
3. If the valve stem is faulty, use a valve stem removal tool to replace it.

4. Reinstall Tire and Check Pressure

Sub-steps:
1. Mount the tire back onto the wheel assembly.
2. Inflate the tire to the manufacturer-recommended pressure using an air compressor.
3. Use a torque wrench to secure the lug nuts to the specified torque settings.

5. Recheck for Leaks

Sub-steps:
1. After installation, perform a soap and water test again on the repair area and valve stem to ensure no air is escaping.
2. Monitor the tire pressure over the next few days.
