I give 1 star for these chains - one chain broke in the snow on the 3rd day of operation. I bought them last year but only used them recently, in the winter of 2015-16 we had a lot of snow in the Tahoe area of California. We were on Christmas vacation, got caught in a heavy snow storm and chain steering was installed on the passes. I put them on and rode normally for two days. Never more than 25 mph. On the 3rd day, as we were leaving the entrance of our home, one of the chains broke. It's good
