These Cobra Jr. cable tire chains are made with tough, low-profile carbon steel rollers to provide traction and long wear. The low-profile of the steel rollers allows increased tire-to-road contact, resulting in better stability as well as considerable noise and vibration reduction. These cable tire chains are designed for use on cars having minimal clearance availability and original equipment tires with highway tread. They are totally galvanized for rust protection and come packed in a cardboard box for easy storage.
