No rings, no hooks, no re-tensioning – snow chain mounting has never been so easy, how is that possible? The solution lies in the unique technology which is placed in the pewag snox-box. At a certain speed, the pewag snox-system locks the ring – the ideal tensioning of the chain is regulated fully automatically. When the vehicle stops, the ring is released again and you can simply pull the chain off the tire. For an even quicker demounting of the chain, the latest generation of this successful snow chain is additionally equipped with the patented quick-release system. Ideal for drivers who want to be prepared for all wintery conditions. The new pewag snox is packed in the hip pewag snox-case. Always on board, always prepared.
