So I am going to be replacing my stock 50 mile Carnivores. It might be easier to just order a set of built wheels and tires as some other folks on here have done. Or, I might just order some tires and have them mounted on my stock wheels @ $50 a pop. Not sure yet which direction I'll go, but if I were to end up selling the stock wheel and tire assemblies as spares, what are they worth? I realize Kawi wants ~$418 for one. Mine have the green rings.
