A flat tire is fixed by pumping the tire up. If this don’t work then you have a hole somewhere. If that is the case you need a jack, something to get the nuts off, and a spare tire. Start by jacking the car up on which ever side the tire is flat on. Then take pliers or whatever you have and start unscrewing those. You should be able to take the tire off after you gets those loosened and in a pile so you don’t loose them. Then take the spare tire and put it on the axil thing. Take the nuts and tighten them as much at you can. Then take the flat tire and put it in your trunk. Go to the nearest auto shop and have them check your work and then buy a new tire!
