<human>:  How do I fix a flat tire?
<bot>: 
1. First, make sure you have all the necessary supplies to fix a flat tire, including a wrench, a jack, and a spare tire with the correct air pressure.
2. Next, loosen the lug nuts on the flat tire with the wrench.
3. Then, use the jack to lift the car off the ground, allowing you to take off the flat tire and replace it with the spare tire.
4. Finally, tighten the lug nuts on the new tire, then lower the car and inflate the spare tire to the correct air pressure.
