How about a different brand of tire? When the tread wears down, are you talking about a bald tire, or are you seeing the weave of the nylon casing? If it is just bald, don't sweat it, since the tread on something as narrow as a bike tire is pretty much cosmetic anyway. As long as you haven't worn through to the casing, the tire should be fine.
