Yachtie, you'd want to check that your insurance covers you with those on though. One of my colleagues was told by her insurance last winter that she wouldn't be covered if she was driving with the snow socks on.
As far as I know, they're only really for getting you out of a situation where you're stuck, then you take them off. Feel free to correct me though, I'm just going by hear-say.
Thanks for that, will have to check out.
