Double Ring tractor tire chains are excellent in loose traction situations like mud and ice. Each individual ring is welded, a second one is laid on it. Then two through it and two through it and so on forming a necklace pattern.
The double rings move freely and are able to edge well in ice. In mud the double rings move within themselves and thus shedding the mud. Similar to kicking mud off your shoes.
Double Rings tire chains are too aggressive for on road (paved) use.
Double ring tire chains may damage the road since they bite so well.
