Using these snow chains is easy. First, make sure your car is parked on a flat and stable surface. Take the chains out of the carrying case. Follow the colour-coded and easy-to-understand fitting instructions. Put on the plastic gloves to keep your hands clean. Attach the chains to your tires and use the manual tensioning feature to secure them properly. The auto-locking device will help keep them in place. When driving, be aware that these chains are designed for icy and snowy roads. Avoid using them on dry roads as it can damage both the chains and your tires. After use, remove the chains and clean them with water to prevent rust. Store them back in the semi - rigid carrying case with velcro in your car boot for future use.
