They are nice tracks if you do not plan on adding aftermarket traction products. In my opinion, the tracks are too soft... which is good for track to snow traction, but bad for studs! The studs rip out very easily. I don't know if the newer ones are better, but the Yoko's I've tried were in the '94 - '95 season.
Unless you are getting a great deal on this Yomo track, I would buy a Camoplast (brand name) and get it over with. They are affordable and very durable.
My opinion--hope it helps.
