I've lived in Canada my entire life and have never put on snow chains. If you don't drive in the mountains or in extreme winter weather conditions, chances are you've never used snow chains either! But in certain winter weather situations, snow chains can be a life-saver and even if you never have to put them on, it's still good to know how.
What are snow chains?
Snow chains are sets of chains that you put on your tires to help with traction on ice or snow. Traction is increased by 100% when you use snow chains correctly; they also make stopping on ice and snow much easier. You can buy them at your local automotive store and they're sold in sets of two.
Snow chains come in a variety of configurations and some are easier to put on than others. Check your owner's manual to see what kind of chains they recommend for your vehicle; and definitely consult a professional when buying snow chains for the first time.
