Thule snow chains are surefooted and safe, as well as remarkably easy to install and remove. They feature dual-sided D-shaped links that provide exceptional traction and extend the life of the product. A patented self-centering and auto-tensioning system activates and the chain tightens around the tire. This system eliminates the need to exit your vehicle and brave the elements to re-adjust the chains for safety and ease of use. For easier installation in the dark or during the day, the Thule CG-9 is constructed with a smaller-sized 9mm D-link chain. Smaller links take up less room, ensuring that they will not bend or damage braking and steering components. They also offer perfect compatibility with electronic brake and traction systems as well. The special anti-scratch nylon bumpers protect your investment by ensuring that the chains never actually come in contact with your wheels.
