Actual tire chains are better than cables. Chains offer better traction and longer life. They also seem to be more corrosion resistant. ... Some vehicles require chains or cables that do not stick out from the tire very far because of limited clearance between the tire and vehicle.

During severe winter storms, CDOT will implement a Passenger Vehicle Chain Law (also known as a Code 16). This is the final safety measure before the highway is closed. When the Passenger Vehicle Chain Law is in effect, every vehicle on the roadway must have chains or an alternative traction device (like AutoSock).
