How do I fix a flat tire on my car?
assistant
First, you need to loosen the lug nuts on the tire. Use a tire iron to loosen them, but don't remove them. 2 Next, jack up the car so that the flat tire is off the ground. Once the flat tire is off the ground, you can remove the lug nuts completely and take off the tire. 3 After the tire is removed, insert the spare tire and tighten the lug nuts. Lower the car and use the tire iron to tighten the lug nuts as much as possible. 4 Finally, inflate the tire to the recommended pressure and you're ready to go.
