Frequently Asked Questions

Check out our Tips for effectiveness below or the PDF. to ensure the best performance and lifespan of your AutoSock.

  • Use the proper AutoSock size for your tires for best performance. Always test fit before using.
  • Avoid excessive speed as it increases wear. Passenger vehicles not to exceed 30mph and commercial vehicles not to exceed 20mph
  • Don’t spin the tires, use a“lightfoot”on the accelerator.
  • AutoSock is designed to increase traction on snow and ice. Driving on dry or damp roads significantly increases wear. Unlike chains, AutoSock is quiet so don’t forget that they are on!
  • Do not leave AutoSock on your tires while parked overnight or parked for long periods when it will freeze.
  • After removal, store wet AutoSocks inside where they will not freeze.
  • Slow down in deeper snow

Avoid excessive speed as it increases wear. Cars not to exceed 30mph and commercial vehicles not to exceed 20mph .

Sizing

AutoSock is a textile tire cover that increases traction on icy and snowy winter roads.  AutoSock is very easy and quick to mount and remove, significantly easier and faster than any metal snow chain.

AutoSock is more effective than winter tires and are also more effective than snow chains in certain situations. They have been tested and formally approved by several leading car manufacturers and ToeV SoeD in Germany. AutoSock can be mounted on summer tires and winter tires (with or without studs).

It is well known that snow and ice sticks to textiles. AutoSock is made from 100% high-technology fibers. These fibers, which become hairier with use, are arranged in a specific pattern in order to optimize grip. The specially developed textile has the advantage of handling water film found between the icy and snowy road and the tyre, (generated for example by heat from the sun, or wheel spin), thereby maximizing the grip.

Tribology/ Dry vs. wet friction

Tribology is defined as the science and technology of interacting surfaces in relative motion and of the practices related thereto.

A tribological system consists of three parts:

  • Upper surface
  • Lubricants
  • Lower surface

In the case of friction on icy or snowy roads the upper surface is the tyre or AutoSock, the lubricant is water film created by frictional melting and liquid layer on the ice/snow, and the lower surface is the icy or snowy road.

When the water film thickness is insignificant, we have dry friction; this is the case when braking a car at -20ºC. When the water film separates the two surfaces, we have wet friction; this is the case when a car water planes. AutoSock wants to have as large area as possible under the AutoSock with dry friction, since dry friction gives the highest friction coefficient.

Snow vs. Ice friction

AutoSock has:

  • A surface pattern that makes the total contact area exposed to friction sufficiently large under both soft and hard snow or ice conditions
  • A combination of surface pattern, strength and elasticity that make the contact points sufficiently sticky under hard snow or ice conditions

To some extent we have a trade off between good friction properties on snow relative to ice. It is favorable to open up the structure in order to increase the total contact area exposed to friction on snow. At the same time the contact points need to be sufficiently sticky on hard ice. The contact configuration of a tyre or AutoSock can be quite different on snow relative to ice.The upper figures show the contact configurations of a tyre on soft snow.The figure to the left simulates compaction resistance, while the figure to the right simulates impact resistance.

The lower figure shows the contact configuration of a tyre on ice where the macroscopic impact and compaction resistances are negligible.

Electrical parameters

The AutoSock is made of a special high friction textile fabric. In a frictional AutoSock sliding situation, electrostatic pressures can be defined in:

  • The air gaps between: a) the sock surface and the icy or snowy road, b) the sock surface and the water film, c) the water film and the icy or snowy road surface.
  • The interfacial contacts between: a) the sock surface and the icy or snowy road surface, b) the sock surface and the water film, c) the water film and the icy or snowy road surface.
  • The water film.

The dry friction process is dominated and characterised by accumulation of electrostatic charges in the slider contact points. The frictional water film initiates discharge of potential differences between the slider and the sliding surface due to the much higher electrical conductivity of water relative to snow/ice.

The topography of the slider and the sliding surface is decisive for the electrical contact configuration between the slider and the sliding surface.

The electrolytic conductivity of a melted snow/ice sample may indicate the rate of ions introduced to the interface between snow/ice and the slider by frictional melting and thereby the rate and ease of discharge between the slider and snow/ice through the frictional water film during braking. Larger frictional electrification should take place on snow/ice with low electrical conductivity compared to snow/ice with high electrical conductivity.

AutoSock does not have the loud rattling and the bumpy ride which you associate with snow chains.  Because there is no danger of damage to vehicle structure, they are approved for speeds up to 30mph for passenger vehicles and 20mph for commercial vehicles; nevertheless your speed should always be appropriate for the weather and road conditions.

They will improve traction on snowy or icy surfaces.  It is recommended that you take them off when you get back to road conditions where no snow or ice is present, e.g. dry or wet asphalt.  During the approval test by TUV, AutoSock passed the distance and durability requirements of snow chain norm (-Norm5117) in addition to the durability requirements for Colorado DOT.  Asphalt and concrete driving is not recommended as it increases fabric wear considerably.

They’re likely to be wet and dirty.  Put them back in their storage bag – gloves are provided.  When you get home, dry them and shake the dirt out.  They are machine washable, but remember to put them back in the car for the next time! Do not leave on overnight or for extended periods with the vehicle parked.

In the U.S., most states do not regulate traction devices for cars and SUVs.  However, where there are traction laws in place, the AutoSock is approved.  Check out your local regulations here.

Yes, AutoSock can be used with all electronic safety systems such as; ESP, ASC+T, ASR, and ABS.  In difference to other traditional firction equipment, AutoSock improves the performance of the electronic safety systems as such.

No, just stop your car and engage the handbrake. Make sure the car is not in a slope during fitting. Pull the AutoSock over the driving tires and downwards as far as possible, and then move the vehicle approx. 1m, to pull the remainder into position. AutoSock will automatically become centered when you start driving. If you are stuck, do as above, but then make a small wheel spin instead of moving the car. For more info, check mounting instructions.

Yes, this is no problem if the AutoSock you have match the tire sizes of your other vehicle. To find the right tire size click here.

Yes, AutoSock is 100% textile material and will not damage your rims.

Yes, AutoSock works even with vehicles which have low clearance between the tire and the body and between the tire and the suspension.

low clearance

Each bag is a pair of AutoSock to cover two tires.  These are mounted on your drive tires.

Yes, place AutoSock on all four wheels.  Variation between 4WD systems is large, some only send a fraction of the power to the front axle no matter what, so you want to make sure all the wheels are covered.

Yes, place the AutoSock on your drive axel.  For front wheel drive, place on front tires.  For rear wheel drive, place on rear wheels.
