The Zip Transport is the best solution for SUVs, VANs, and Campers driving on snowy roads. It features a 16mm thickness internally and across the chain, increasing its resistance to wear. The internal flexible cable allows the chain to be fitted without moving the vehicle in just 3 minutes. The manual tensioning system requires a stop to retighten the chain after a few meters following assembly. The additional links at the front of the chain allow the chain to be adjusted to different tire sizes, brands, and models, as well as tires with varying levels of wear. Certifications: Ö-Norm V5117, Ö-Norm V5119, UNI 11313. Note: It is recommended to perform a trial installation in good weather conditions for familiarity before fitting them in snow.
