1. First, make sure you are in a safe place and the car is parked.
2. Loosen the lug nuts with a lug wrench before you raise the car with a car jack.
3. Raise the car off the ground until the flat tire can clear the surface.
4. Replace the flat tire with the spare and put the lug nuts back on.
5. Lower the car and tighten the lug nuts in a star pattern.
6. Finally, check the pressure of the spare tire and store the flat tire.
