From the picture, looks like the side chains need to be tighter (shortened) by taking in more links. Extra links are cut off on the inside so nothing flopping around, and because the extra ones may be needed for tightening on the outside, they can be wired back so they don't flop (and bang on the fender).
The springloaded cross tighteners look a bit flimsy, IMO and you may find that in deep snow and icy snow chunks, they will be ripped off. As mentioned, I sometimes add some bungee cords to take up some slop, but mostly tighten the side chains to take up the slack.
Just an observation, and can take it for what it might be worth to you. /forums/images/graemlins/wink.gif In icy conditions, chains are often a must, and the scratches in the asphalt get covered when the new sealer is applied. Deep scratches from getting 'unstuck' are harder to hide with sealer /forums/images/graemlins/tongue.gif beenthere /forums/images/graemlins/grin.gif
