Wish I had better advice for you... but I never paid much attention to the chains. I used to have a plow truck that I had chains on when the road were a rink. All I can say is pretty much any set of chins work. Best I can sey is get a set thats a good fit. We had one guy who had a loose set on his tires, broke off somehow and wrecked the side of his box.
Also, make sure your allowed to run them on the orad where you are. Up here we can't, I got pulled over for them more than once.
