Do not use bare hands on cold, icy chains. Drive very slow and deliberate with chains on to gain proper traction and control on the icy trail. These chains must be sized according to the tire. They are very specific for tire size, i.e., not generic sizing. Whether you use your rig to navigate wintry streets to get groceries and the kids to school, or winch to that great ice fishing spot, you need to be prepared for any incident.
Winter is nothing to be trifled with.
Have the proper equipment and a plan on how to use it, if necessary. Get proper training in vehicle operation. Take some emergency training through your local Red Cross office. Be aware of your limitations and those of your vehicle. No matter what kind of rig you own, from stock showroom vehicle to the most radical of off-road machines, you must always check it out before heading to the hills.
