We use chains on our E350 service vans, admittedly, in Seattle, we don't use them every year, but due to micro climates, and HILLS when we do get snow, often we end up chaining up. We've tried a lot of cable chains, etc, bottom line, there's no substitute for real chains. A lot of the quickie, or alternative type products won't take driving for long distances, they're okay if you need to go a couple blocks to a plowed road, but if you're going to be traveling any distance, they just don't hold up.
