<human>:  How do I change a flat tire on my car?
<bot>: 
1. First, you will need to make sure that you have a jack and a wrench.
2. Lift your vehicle up with the jack so that you can place a jack stand underneath.
3. Loosen the wheel nuts with the wrench, taking care not to completely remove them.
4. Remove the wheel from the car and put the spare tire in its place.
5. Tighten the wheel nuts with the wrench and lower the car onto the ground.
6. Finally, use the wrench again to fully tighten the wheel nuts.
