I purchased mine from Amazon 3 years ago. They are Classic Deluxe brand. I paid about $45 for a set of four. I have 22.5 inch tires so they are larger than what you would need. They are in perfect condition after 3 winters. I don't even tie them on because the elastic holds them well enough. Since only one side faces the sun I don't use all 4 so I should get twice as long life from the set.
