How do I fix a flat tire on my BMW?

I was driving my BMW when suddenly I got a flat tire. I have no idea how to fix it on my own. What should I do?

First, make sure you have a spare tire and tire changing tools in your car. Then, find a safe place to park your car and engage your emergency brake. Next, remove the hubcap and loosen the lug nuts a little bit with a wrench. After that, use a jack to lift your car off the ground and remove the lug nuts completely. Carefully take off the flat tire and replace it with the spare. Finally, tighten the lug nuts, lower the car, and replace the hubcap. It's always a good idea to practice changing a tire before a situation like this arises.
