I'm old enough to remember chains being heavy, bulky and impossible to assemble without getting muddy and snowy. This is an EVOLVED product that solves all the old problems. Also, they have minimal clearance requirements - they work great on my Ford Focus which claims it can't use chains. Oh, but this useless set of European installation instructions is all illustrations. Fortunately, it's easy to find videos on You Tube to learn how to install them. Make sure you study on a good day when there is no snow or ice!
