Solution

1. Preparation

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

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve cap from each tire.
2. Use a tire pressure gauge to measure the current pressure.
3. Compare the readings to the recommended tire pressure (found in the owner’s manual or door jamb).
4. Inflate tires to the correct pressure using an air compressor.
5. Re-check the pressure after inflation to ensure accuracy.
6. Replace the valve caps securely.

3. Inspect and Replace Damaged Tires

Sub-steps:
1. Thoroughly inspect each tire for visible punctures, cracks, or bulges.
2. If damage is found, consult with a professional to determine if repair or replacement is necessary.
3. Replace any damaged tires with the appropriate size and type as specified by the manufacturer.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Locate the TPMS reset button (usually found under the steering wheel).
3. Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
4. Drive the vehicle for a short distance (about 10 minutes) to allow the system to recalibrate.
