Solution

1. Preparation

Gather necessary tools: tire pressure gauge, tire repair kit, air compressor, and possibly a torque wrench.
Ensure the vehicle is parked on a flat surface and that the tires are cool for accurate pressure readings.

2. Inspect and Repair Tires

Check for Punctures:
- Visually inspect each tire for nails or sharp objects.
- If a puncture is found, use the tire repair kit to seal it.
- If the damage is severe, consider replacing the tire.
Inspect Valve Stems:
- Remove the valve cap and check for cracks or leaks.
- If damaged, replace the valve stem with a new one.
Check Tire Pressure:
- Inflate the tires to the manufacturer-recommended pressure (found on the driver’s side door jamb).
- Use the tire pressure gauge to ensure correct pressure.

3. Check Rims

Inspect the rims for any signs of corrosion or damage.
Clean any corrosion using a wire brush.
If rims are damaged beyond repair, replace them.

4. Monitor and Reset TPMS

Reset the TPMS:
- After ensuring all tires are properly inflated, reset the TPMS according to the vehicle's manual.
- Drive the vehicle for a short distance to allow the system to recalibrate.
