Also quickly on and off. You can put these chains on without getting dirty, as contact with the tires and wheel arches is kept to a minimum thanks to the construction of the chains. I use them on my Mark VII GTI as little as possible to get myself out of stupid situations I've gotten myself into negligently. I try to plan ahead and use my 4x4 when driving the course in bad conditions, but sometimes nature wins. They are easy to clean and pack into an attractive case that fits comfortably on my back with my dogs, along with a shovel, rescue harness, extra winter clothing and a flashlight. Getting ready!
