Solution

1. Preparation

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

2. Inspect and Repair Tires

Visual Inspection:
- Examine each tire for punctures, cuts, or foreign objects embedded in the tread.
Repair Punctures:
- If a puncture is found, remove the object using pliers.
- Clean the area around the puncture.
- Apply a tire plug or patch kit according to manufacturer instructions.
Check Valve Stems:
- Remove the valve cap and apply soapy water to the valve stem. Look for bubbles indicating a leak.
- If leaking, replace the valve stem.
  - Tools Required: Valve core tool, replacement valve stem.

3. Inspect Wheel Rims

Check for Damage:
- Inspect the rims for dents or corrosion that may prevent a proper seal.
- If damage is found, consider replacing the rim.

4. Bead Seating

Re-seat the Tires:
- If tires are not seated properly, deflate the tire, clean the bead area, and inflate while ensuring the tire seats correctly on the rim.
  - Tools Required: Tire inflator, tire bead lubricant.

5. Regular Maintenance

Inflate tires to the manufacturer-recommended pressure before driving.
Rotate tires every 5,000-7,500 miles to ensure even wear.
