Changing a tire on a car can be a relatively simple process, but it's important to know the basic steps and have the proper tools before starting. Here's a general overview of how to change a tire on a car:
Find a safe location to change the tire. Make sure you are on level ground and away from traffic. Turn on your emergency flashers to warn other drivers that you are changing your tire.
Locate the jack, lug wrench, and spare tire in your vehicle. They are usually located in the trunk or in a dedicated storage compartment. Make sure that you know where they are located before you have a flat tire.
Loosen the lug nuts. Use the lug wrench to turn the lug nuts counterclockwise to loosen them. Do not remove them yet.
Raise the vehicle. Use the jack to lift the vehicle off the ground. It's important to be sure the car is stable and that the jack is in the correct place.
Remove the lug nuts and take off the flat tire. Carefully remove the lug nuts, and then gently pull the flat tire away from the car.
Install the spare tire. Line up the holes in the spare tire with the studs on the car, and press it firmly onto the car. Replace the lug nuts by turning them clockwise with the wrench.
Lower the vehicle. Use the jack to lower the car back to the ground.
Tighten the lug nuts. Once the vehicle is back on the ground, use the lug wrench to turn the lug nuts clockwise to tighten them.
Drive to a repair shop or a tire store as soon as possible.
It is important to keep in mind that spare tires are not meant to be used long term, they are only temporary solutions. They usually have a lower speed rating and less tread than regular tires. Also, do not overload the car and check the pressure on the spare tire frequently.
