In sliding asphalt conditions, the aim is bringing the grip properties back to the tyre. This aim can be achieved in several ways:

• Metallic chains and spikes spider, their function is covering the tyre to avoid making the wheel run on the snow. They let the chain settle on the ground so the tyre can make traction. The chain nails the snow, cutting it and looking for the hard support of the bottom.
• ISSE textile tyre chains also cover the tyre, but their function is explained by a tribologic system, defined by three variables:
  • Upper surface.
  • Lubricant.
  • Lower surface.

In snowy or icy roads, the upper surface would be the ISSE covered tyre, the lubricant is the water film formed by snow or ice fusion due to the friction, and the lower surface is the snow or ice layer of the road. Depending on the amount of lubricant between both layers, we would talk of dry or wet friction. The drier the friction is, better the vehicle stability and smaller the braking distance will be. ISSE increases to the maximum the existent dry-friction area.

This is achieved thanks to both its fabric composition and its structure.

Fabric structure :

Its grid form increases the contact surface between the pieces, so as the grip also increases.

Its composition, high-resistance fabric, improves its durability and makes it absorb water, so as to
reduce the amount of lubricant between the parts in contact, which increases the grip.

ISSE textile tyre chains are made to improve the already existent products, and to avoid the harming consequences on the tyre and different parts of the vehicle that can sometimes take place. It is also intended to make its use and assembling easier. When making this product, several analyses and tests where performed in collaboration with several laboratories, which has allowed us to achieve a patented, approved and highly reliable product.
