Solution

1. Preparation

Gather tools such as a tire pressure gauge, soapy water solution, and a tire repair kit.
Ensure the vehicle is parked on a level surface and the tires are cold.

2. Inspect and Repair Tires

Visual Inspection
- Check each tire for visible damage like cuts or punctures.
- Remove any foreign objects embedded in the tread.
Leak Testing
- Spray the soapy water solution around the tire and valve stem.
- Look for bubbles forming, indicating an air leak.
Repairing Punctures
- If a puncture is found in the tread area, use a tire plug or patch kit to seal it.
- For damage on the sidewall, consider replacing the tire.

3. Valve Stem Inspection and Replacement

Check Valve Stems
- Remove the valve cap and inspect the stem for cracks or damage.
- If damaged, remove the old valve stem using a valve stem tool and install a new one.

4. Tire Re-seating (if necessary)

Re-seating Tires
- If the tire beads are not seated properly, deflate the tire completely.
- Remove the tire from the rim and clean the bead area.
- Re-mount the tire on the rim and inflate to the recommended pressure.

5. Reset TPMS

After completing repairs, reset the TPMS following the vehicle's manual instructions to ensure accurate pressure readings.
