I use these on all my vehicles but initially bought them for my BMW. Chains tear up delicate sensors and can do damage to the suspension parts, so are not recommended by BMW. And, if you've ever been stranded somewhere trying to put chains on in the cold- it's a nightmare! Enter the Auto Sock. When I purchased my first pair, I don't think many knew about them in my area. They were so easy, but how could they work so well? I was able to drive up hills with ice, in my little car, while 4X4's were spinning out all around me WITH snow tires on! The look on the other drivers faces was priceless!As a nurse, when I get called in to work, I can't say no due to snow and ice- I have to be able to get off my hill. These make that possible, and do it with ease. I even use them on my Subaru for even better traction on icy surfaces. They give me such piece of mind that I recommend them to everyone I know. With a recent large snow storm, my city was paralyzed. I actually gave my old pair (8 years old, used many times with only a dime sized hole in them) to a young woman who couldn't get up my hill and had been trying to for over an hour. I think they were a little big for her tires, but her smile as she drove off easily was worth the effort.If where you live ever gets snow or ice, get these- no matter what type of vehicle you use. They truly are the easiest things to put on and pull off. They are very durable, and the same price as chains. And, I've never seen a snow sock laying in the middle of the road like I do chains. Another plus is unlike snow tires that take up a large amount of room in the garage, they also don't tear up the roads when the pavement is dry. I wish they made these mandatory for people who don't have experience driving in snow- there would be a lot less accidents and stranded motorists out there. If you are looking for a great birthday or Christmas present for your kids going off to college, or anyone you care about- these are not sexy and probably not on anyones's list, but they are a great gift that will keep someone safe.
