Solution

1. Preparation

Gather Tools and Materials:
- Tire iron or lug wrench
- Jack and jack stands
- Tire repair kit or replacement tire
- Air compressor or tire inflator
- Gloves and safety goggles
Safety Warning: Ensure the vehicle is on a flat surface and turn on hazard lights.

2. Remove the Flat Tire

Loosen Lug Nuts:
- Using the tire iron, loosen all lug nuts while the tire is still on the ground (turn counterclockwise).
Lift the Vehicle:
- Place the jack under the designated lifting point and raise the vehicle until the tire is off the ground.
Remove Lug Nuts and Tire:
- Completely remove the loosened lug nuts and carefully take off the flat tire.

3. Repair or Replace

Repair (if applicable):
- For small punctures, follow the tire repair kit instructions to clean the puncture, apply a patch or plug, and seal it.
Replacement (if repair is not feasible):
- Place the new or repaired tire onto the wheel hub, aligning the holes with the bolts.

4. Reinstall the Tire

Secure the Lug Nuts:
- Hand-tighten the lug nuts onto the wheel bolts.
Lower the Vehicle:
- Carefully lower the vehicle back to the ground using the jack.
Torque the Lug Nuts:
- Once the vehicle is on the ground, use the tire iron to tighten the lug nuts in a crisscross pattern to the manufacturer’s specified torque (typically around 80-100 ft-lbs).

5. Inflate the Tire

Check Tire Pressure:
- Use an air compressor to inflate the tire to the recommended tire pressure (usually found on the driver’s door jamb).
Inspect for Leaks:
- After inflating, inspect the repair or replacement area for any signs of air escaping.
