How does one change a flat tire?
assistant
To change a flat tire, you should start by loosening the lug nuts with a lug wrench. Then, you should use a jack to lift the vehicle up until the flat tire is off the ground. Once the tire is off the ground, you can remove the lug nuts that are still attached and then take off the flat tire. Finally, you can place the spare tire onto the wheel and secure it with the lug nuts before lowering the car and retightening the lug nuts.
