<human>:  How do you change a flat tire?
<bot>: To change a flat tire, you will need a jack, wheel wrench, and a spare tire. Start by jacking up the car so that the wheel is off the ground. Next, loosen the lug nuts with the wheel wrench and remove them. Pull the wheel off and replace it with the spare tire. Place the lug nuts back on the wheel and tighten them with the wheel wrench. Lower the jack and you are finished.
