ok, so heres the plan: I found 2 1986(i think) Schwinn world Sports on the side of the road one day. My plan is to take them and make a single speed(NOT fixed-already have one of those) school commuter. Now I live in New Hampshire, and will be at school during the winter, so Im not about to put 23's on this...Im thinking wider cross tires(because I figure the usual MTB tires/wheels wont fit)....

basicially, I just want to know if anyone has any idea what size wheel/tire compbo I should get for this.

Im going to keep most everything else "stock" on it. maybe rattle can the frame, but who knows yet.
