My wife has a Passat wagon we bought new in 2002. It doesn’t have enough tire clearance for chains so I bought spiders and I’ve mounted the plates every year since. Never used them in the snow, though.
Kind of tricky to clamp the plates on the first time – once you’ve adjusted it to fit your wheels it’s easier. I really doubt that they’d survive driving on dry pavement the way people do with chains around here, but if all you need is 100 feet to get out of a driveway they’d work.
