Solution

1. Preparation

Gather necessary tools: tire pressure gauge, air compressor, valve stem tool, and tire sealant (if applicable).
Ensure the vehicle is parked on a level surface and the tires are cool to the touch.

2. Inflate Tires

Sub-steps:
1. Refer to the manufacturer's specifications for the correct tire pressure (usually found on the driver’s door jamb).
2. Remove the valve stem cap from the tire with low pressure.
3. Use the air compressor to inflate the tire to the recommended pressure.
4. Recheck the tire pressure with the pressure gauge to ensure it is at the desired level.
5. Replace the valve stem cap securely.

3. Repair or Replace Damaged Tires

Sub-steps:
1. If a tire is found to be damaged or punctured, assess whether it can be repaired or needs to be replaced.
2. For a small puncture, use a tire repair kit to seal the hole if it meets repair standards.
3. For severe damage or sidewall punctures, remove the damaged tire using a jack and tire iron.
4. Install a new tire as per manufacturer specifications, ensuring proper bead seating.
5. Torque the lug nuts to the manufacturer’s specified torque value.

4. Reset TPMS (if necessary)

Sub-steps:
1. Turn on the vehicle and access the touchscreen display.
2. Navigate to the "Service" menu, then select "Tire Pressure Monitor."
3. Follow the prompts to reset the TPMS, confirming that the tire pressures are now correct.
