Query: WARNING -- Does not fit 205/50R17 tires!!

I bought these chains based on the great reviews on Amazon. But like another customer had stated, these chains were too small to fit on my 205/50R17 tires despite the fact that my size was listed as compatible on the product AND I followed the installation instructions to the letter. I eventually had to go to a local auto store and pay full price ($30 more than the Amazon price) for ones that fit. What a waste of time. So if you have 205/50R17 tires, you need the Super Z6 model SZ131.Other than that, the product was of very good quality and neatly packed in a nylon bag including instructions and plastic gloves.
