Years ago, I had some things like tire chains, but there was no metal involved. There were cleats that ran across the tire, and they were made out of hard rubber, or plastic. (It was yellow, not sure what the actual material was) They had straps to hold them onto the wheel, sort of like tire chains. They weren't as good as metal chains, especially on ice or packed snow. But they didn't hurt the tire, and they didn't wear out quickly, when you drove them on dry pavement. Also, if one of them broke, the loose end flopping around wouldn't do a lot of damage, unlike "real" tire chains. Plus, they were very light, so you could carry them in the trunk "just in case". They were great for North Carolina, where it snows rarely, and the snow melts quickly. For those of us who use our Buicks as daily drivers, they would be a good thing to have, for those times when you can't avoid going out, even though you would rather be driving something else. But now I can't find the things. Anybody know where I might get some?
