Next, we’ll cover when to use tire chains. This is pretty simple. When you reach an area where snow and ice is on the roadway, or when you’re informed by signs that chains are required, pull over and put the chains on. We have videos available with each of the chains we sell that show you exactly how to put the chains on your vehicle. You should use chains on at least two of your tires. For example, if your car is front wheel drive, use them on the front wheels. If you have two sets of chains available, use both sets. Using chains on all four wheels will provide even better handling and traction.
