Typically, you're not at home, you're on the side of the road. 

There is never a good time for your vehicle to get a flat tire; but some moments are worse than others. In an ideal scenario, you will find yourself with no other traffic in sight, on a wide paved road, on a sunny warm afternoon. Change any (or several) of those parameters though, and getting out to change the tire becomes a perilous situation.

1. Pull over to a safe location away from traffic.
2. Turn on your hazard lights to warn other drivers that you are on the side of the road.
3. Use the jack provided with your car to lift the vehicle off the ground.
4. Remove the hubcap or lug cover if your car has one, and loosen the lug nuts with a lug wrench.
5. Take off the flat tire and put on the spare tire, making sure it is facing the correct way.
6. Tighten the lug nuts with the lug wrench, making sure they are secure.
7. Lower the car back to the ground using the jack.
8. Tighten the lug nuts again using the lug wrench while the car is still on the ground.
9. Put the hubcap or lug cover back on if your car has one.
10. Drive to a tire repair shop or dealership as soon as possible to have the flat tire repaired or replaced.
