I bought these tracks before winter when I was selling my jeep 4x4. I've used them on both my 2003 VW Passat sedan and 2008 Passat station wagon. With everyone either paying $30 to have their chains installed or laying in the snow under the cars, I got out of the car and came back in 4 minutes max and was completely dry. They are incredibly easy to install and stayed put from the moment I installed them to the moment I took them off 20 miles later. Just a few tips. one). Make sure you put them on before you travel. While the directions (pictures) aren't perfect, they're less than perfect when you're trying to figure them out on a busy mountain road. 2) After placing them on the curb, drive about 50 feet to make sure they are properly seated on the tire. I usually just had to push/move the chain a bit on one of the levers to get it in place. THAT'S IT! Now I can't wait until next winter when I can use them again. I don't miss my 4x4 at all.
