The 'ROTOGRIP' automatic snow chain system is a new piece of equipment that will enable drivers to activate the chain system only when it's required. This does away with the need for chains to be affixed onto tires on a permanent basis until removes to only have them operate when required.
The 'ROTOGRIP' chains work by being installed underneath vehicles near the tires. When activated from inside the car cabin, the 'ROTOGRIP' instantly goes to work by rotating a chain assembly that will add additional grip when required. The 'ROTOGRIP' automatic snow chain system is purported to provide an additional 45% more traction without having to fully install traditional steel chains on your all-season or winter tires.
