Ok! Thought that I had bought the Razor 2 rear tires but was told by a friend of mine that they were actually Razor tires which she was right, I guess. Supposedly the Razor 2 tires have the "2" part of the logo so I check on some web sites but they only show the front/rear side of it and by lookng at them, can not tell the difference (thread or plys) difference between them. Does anyone actually know the difference between the original Razors and Razors 2 tires.
