AutoSock for cars fits well on vehicles with low clearance in the tire house and works perfectly with optional tires – even when snow chains are not recommended. AutoSock for cars comes in 10 different sizes, covering more than 500 of the most popular tire dimensions.

HIGHEST PRODUCT QUALITY IN ALL COMPONENTS

1 2

Front Fabric
The woven and coated net stabilizes the entire AutoSock and prevents snow or debris from gathering between the tire and the road contact fabric.
Straps
The straps give the snow sock its signature look. They assist mounting and demounting the product and add stability.
Road Contact Fabric
The unique fabric construction, provides a long product life and an outstanding friction. The arranged fibres facilitate the textile to absorb any water between the ground and the tire, thereby maximizing the dry friction grip.
Inner Fabric
Usually used for high quality parachutes, the inner fabric holds AutoSock in position, assures proper fit on the tire and supports the black elastic strap to reach its ideal position behind the tire for optimal tension.
Elastic
The elastic keeps the tire sock in position, supports self-centering and assures stable fit to the tire. The combination of tenacity, elongation force and elasticity for best performance was evaluated in extensive tests during the development of AutoSock.

HOW DOES IT WORK?

Textiles tend to stick to dry snow and ice. The arranged fibres, used for the road contact fabric of AutoSock, facilitate the textile to absorb and ‘wick away’ any water between the ground and the tire, thereby maximizing the dry friction grip. Each thread of the road contact fabric consists of more than 100 fine high-performance fibres, which lead to a “hairy” surface of the AutoSock traction fabric. These “hairs” penetrate the slippery water film and connect the tires directly to the surface (snow). With correct use, AutoSock becomes “hairier” and even improves performance over time.
