I purchased these this past Summer when they are at their cheapest, and used them yesterday (1/2/2014). The roads got worse and worse until cars were literally sliding sideways off the road due to ice, and the snow was still falling fast. I found a (relatively) safe place to pull over, in front of another vehicle with headlights on to help me put them on, got back on the road then I navigated the icy hills and curves with no problem at all. Other cars were doing crazy things all around me. I used mine for 11 miles, the last 9 of which were plowed/salted (didn't feel like taking them off). They were on as tight at the end as the beginning. The ride is very bumpy if you're not going over packed ice and snow.Of course when I got them I tried them to make sure they fit OK, which they did. Some listings have more than one application for the same size tire. If your tire size is one of these, this is a clue that you really have to be careful about fit.After using them, rinse with tap water and then lay them out under a lamp to dry. Then spray them with FluidFilm to prevent rust. You can use WD40 to help get them dry, but it will do nothing to prevent rust beyond that.Pro-Tips:1. Order in Spring or Summer for best price.2. Install one in nice weather. Paint the connector segment that corresponds to ideal tension a bright color.3. Put a pair of work gloves in the box with the chains. Disposable heavy duty rubber gloves are best because they have enough feel to do the connections.4. Keep a tarp, or use a floor mat while installing in bad weather. (I keep a small tarp under a floor mat)5. To install easily, put on top of tire and then push all the way over onto the axle. Pull the far side connector back and hook it up, then pull it back over tire and install near side connector.6. I found that 4 (2 sets) of SC1030 will just fit in one box, if you lay them all on top of each other and roll them up together. This may vary by model.Finally, putting on chains in bad weather is a hassle, taking them off once you reach a plowed road is a hassle, and there will always be bad reviews from folks who got the wrong size (for whatever reason). But when the roads are icy and crazy, there's no substitute, not even studded Winter Tires will do as well.
