Together with technological innovation constantly evolving, it’s no wonder these automatic tire chains currently have made a splash in the tire chain industry. These kinds of tire chains eliminate the agony of affixing tire chains in freezing or wet conditions, and will help save motorists a lot of time.
To set up automatic tire chains, motorists attach an electric switch mounted to the dashboard, which offers 12 volts for an air solenoid installed on the frame rail of the vehicle. Pressurized air is then delivered from the vehicle’s 12 volt compressor or onboard air system. Once the dashboard switch is triggered, the solenoid opens, therefore enabling pressurized air to begin flowing to the air cylinder and reduce the chain wheel in order that it contacts the interior of your tire.
