Last week, we asked if you had a roadside emergency kit in your cars, and if your kit includes tire changing tools. This week, we ask, “Do you know how to use the tools?” We found a very good article, with lots of pictures, from WikiHow on how to change a tire. Maybe you could make practicing tire changing a family activity this weekend and have some fun with it. Think NASCAR! Most folks plan to call AAA first anyway, but you never know if your mobile phone is going to work or how long it could take to for help to arrive.
