Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Wear safety gloves and goggles.

2. Tire Inspection and Repair

Inspect Tires
- Visually examine each tire for punctures and sidewall damage.
- Mark any visible damage for repair or replacement.
Check Valve Stems
- Remove the valve cap.
- Apply soapy water to the valve stem; look for bubbles indicating a leak.
- If leaking, replace the valve stem.
Repair Punctures
- For small punctures, use a tire repair kit to plug the hole.
- Follow the kit instructions; make sure to clean the area around the puncture before applying the plug.
Reinflate Tires
- Inflate the tires to the manufacturer-recommended pressure using an air compressor.
- Check pressure with a tire gauge after inflating.
Inspect Wheel Rims
- Clean any corrosion from the rim surface.
- If the rim is damaged, consider replacing it or have it professionally repaired.
Reinstall Tires
- If tire bead is not seated properly, deflate the tire, reseat the bead, and reinflate.
- Ensure tires are mounted and balanced correctly.
