As most know, I am mostly a Mtn/dh rider. But I do love to ride, so I have the roadie. I am looking for a tire to use with the trainer, call me cheap but I dont feel like wearing out My diamonte's and putting wear on my good wheels so I am going to put something on my spare wheel, the one with the crazy ass radial/3x lacing, for using on the trainer. At the same time, I want something that will last and dont feel like spending a fortune. Feel free to laugh at me, but I just dont know road tires enough. Edit...Where can I get those Airless things??? Is that the whole tire? or is it like the walmart neverflats?
