OK admittedly I haven't read all 38 pages of posts on this, but just to say I moved to Portland area in OR, and went to go to Mt. Hood snowboarding. The rain we had was snow up there and the sign required snow tires or chains. I turned around and talked to a shop who sold chains, we checked the owners manual and it specifically says do NOT use chains. I looked carefully at the car to see why and discovered the strut spring seat was pretty close to the tire tread. I drove home

and stopped on the way to see about finding kids ski equipment at a used stuff store and found some cable type chains for $7 that would fit the sonic LTZ. they were a lot thinner than the chains.
I turned back around and got to the snowy chain-up area. I mounted them as tight as I could, and used a rubber bungee to add additional tension. It worked well, but I got enough clicking of the junction knocking against the strut over 25 I decided (it was also getting super late for hitting the slopes) to turn around.
Anyway, for short distances in some situations at low speed, with added bungee tension, you can use cable chains for emergency purposes. I'm wondering how they do next time if I really get them tight on back side and secure the free end better.
Yes, I would be better off getting snow tires, but more than likely I'd be using my other vehicle most of the time so I'd put the tires on that.
A lot of folks here use studded, but with the noise and all no advantage on snow, I'm just going to possibly get a AWD vehicle, get snow treads and drive conservatively.
