Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Wear safety glasses and gloves when handling tires.

2. Tire Inspection and Repair

Sub-steps:
1. Remove the tire from the vehicle using a jack and a lug wrench.
2. Inspect the tire tread and sidewalls for punctures or foreign objects.
3. If a puncture is found, determine if it is repairable (less than 1/4 inch; located in the tread).
4. If repairable, use a tire repair kit to seal the puncture. Follow the kit instructions for proper application.

3. Valve Stem Replacement

Sub-steps:
1. If the valve stem is damaged, remove the tire from the wheel (if not already done).
2. Use a valve stem tool to extract the damaged valve stem.
3. Insert a new valve stem and ensure it is seated correctly.
4. Inflate the tire to the manufacturer’s recommended pressure.

4. Rim Inspection and Repair

Sub-steps:
1. If the rim is cracked or corroded, consider replacing it.
2. If minor corrosion is present, clean the rim with a wire brush and apply rust-inhibiting paint.
3. Ensure the rim is smooth and free of debris before re-mounting the tire.

5. Reinstallation

Sub-steps:
1. Re-mount the tire onto the wheel, ensuring the tire bead seats properly.
2. Inflate the tire to the recommended pressure.
3. Reinstall the tire on the vehicle and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
