Do you drive? Or even drive in a car often? If the answer is yes then my next question applies to you. Do you know how to maintain your car? Many years ago, I was driving with my cousin when her tire blew out. She had no idea what to do besides call roadside assistance. The wait time was 5 hours! But even though I did not own a car at the time, I did get some great lessons in basic car maintenance including how to change a tire. So I pulled out all the equipment needed which was in her trunk, rolled up my sleeves and changed her tire.
Knowing how to change a flat tire is on my short list of easy car maintenance tips everyone should know. Tell me which ones on the list you know how to do. And for everything else, do see a professional.
