There isn’t really much of a difference. These terms have evolved over time and with the development of new technology. These days, they are most commonly referred to as winter tyres, because their benefits can be felt not only on snowy roads, but in all winter conditions, in particular on wet road surfaces at temperatures < 7°C.
What is the difference between snow chains and snow socks?
The main difference is in the design: snow chains are added on top of the tyre tread, while snow socks completely cover the wheels. With snow chains, the grip is a result of the tyre and the chain working together. With snow socks, it is the fabric material of the sock that provides grip.
On hard pack snow, the 2 systems work about the same, whereas on fresh snow and black ice, chains are more effective. They are also more resistant and will deteriorate more slowly on roads that have been cleared of snow. Socks, however, are much easier and faster to put into place.
Until the early 2000s, you could only find metallic chains on the market. For the past fifteen years or so, however, notably at the instigation of Michelin, new concepts of chains—such as socks (S.O.S Grip) and composite chains (Michelin Easy Grip)—have been developed for easier usage, particularly in terms of installation and continually improving performance.

Do you need special wheels for winter tyres?
You can install your winter tyres on your usual wheels. For drivers who use winter tyres, Michelin suggests you use summer tyres in the summertime, which means you will have to change your tyres twice per year:
- Once in the spring to change from winter tyres to summer tyres
- Once in the autumn to change from summer tyres to winter tyres
Of course, changing your tyres comes at a certain cost. One alternative is to have two sets of wheels (rims + tyres), one with winter tyres and one with summer tyres. This way, you can simply change out your wheels without having to remove your tyres, saving you money.
