This automatic tire chain system offers the traction of a single set of snow chains at the touch of a button, without having to stop the vehicle. An electric switch mounted in the cab provides 12 volts to an air solenoid mounted on the vehicle's frame rail. Compressed air to the solenoid is supplied from either the vehicle's onboard air system or a 12-volt compressor kit.

When the dashboard switch is activated the solenoid opens, allowing compressed air to enter the air cylinder and lower the chainwheel so it contacts the inside of the tire. The friction between the tire and the rubber-covered chainwheel causes the chainwheel to rotate, creating enough centrifugal force to flail the chains out in front of the tire.
