How do I fix a flat tire?
assistant
To fix a flat tire, you will need some basic tools such as a tire iron, a tire jack, and a lug wrench. You will also need to have a spare tire. Start by loosening the lug nuts with the lug wrench, then raise the car off the ground with the tire jack and remove the lug nuts and the wheel. Put the spare wheel onto the wheel hub, and replace the lug nuts, making sure to tighten them with the tire iron. Lower the car and check that the lug nuts are firmly attached. Finally, inflate the tire to the correct air pressure.
