RUD Rotogrip Automatic Traction Chains
Automatic tire chains were designed to give you traction on ice and snow pack at the flip of a switch. The speed of the vehicle causes the chains on the chain wheel to lift by centrifugal force; the weight of the chain determines the speed at which they lift and go under the tire. RUD Rotogrip chain wheels use a smaller chain which will lift at 3 to 4 MPH, and up to speeds of 30 MPH. The wheel has a flat surface which contacts the drive tire so that it has more surface area for less slippage. The chain wheel contacts the drive tire around 4 inches above the ground, thus if the snow is less than 4 inches they will perform as they should. If the snow depth is greater than 4 inches, the snow will stop the chains from lifting and going under the tire. Automatic chain systems will correctly function well if the snow is light and powdery, but if the snow is heavy and wet it may stop the chains from lifting and going under the tire. In mountain driving you may not encounter ice until you reach the higher elevations, but with the flip of a switch you will be ready for the icy conditions. Automatic chains save time because you will no longer need to stop to install and remove the tire chain wraps, thus preventing the potential hazard of being struck by other drivers while outside of your vehicle.
