This innovative, patented product is TÜV and ÖNORM 5121 approved, and complies with B26 legislation. Quick to fit and easy to carry, they are designed to protect your alloy wheels. They provide comfortable driving without vibrations, unlike metal snow chains, and allow a maximum speed of 50 km/h. Suitable for emergency situations, particularly after heavy snowfall, they are suitable for cars, vans and 4x4s. Thanks to exclusive TriboTek and Activ3D technologies, they guarantee very good grip on snow, even in large quantities. However, it is recommended to remove them as soon as the road is dry to avoid any risk of damage. In terms of features, they stand out for easy fitting, effective grip on snow and ice, as well as long service life. Their polyolefin composition allows machine washing at 30°C. Fitting instructions: pull the sock over the tyre like a cover, adjust it correctly downwards, then move the vehicle forward slightly to cover the tyre completely.
