Snow chain characteristics decide how a snow chain is fitted to a wheel.
Fast & easy
It's the easiest, fastest and most intuitive way of fitting a snow chain on your car. Just put it on the wheel starting from the top. Then, simply push the pedal down with your foot and you can continue your trip.
External
The chain is fixed on the external side of the wheel, on one of the wheel nuts. You work only on the external side of the wheel and there are no elements behind. This chain model is particularly recommended for car/SUV with limited clearence behind the wheel.
Traditional - 2 stops fitting
The snow chain is fitted by first laying it behind the wheel on the ground. Then link a few parts to fit it on the wheel. A second stop of the car is required after 100mt to re-tight the chain.
Traditional - 1 stop fitting
You just have to stop your car once to fit the snow chain and then you can drive on safely. The chain will automatically get tightened while you drive.
