i'm not expert but stretching a smaller tire on a fat rim is not a good idea even if it would work , but how long would the tire last & saftey may be a factor
3" wide tire could work but i would not go any smaller
are you looking for bike repair manuels for bikes like schwinn or other brands of bike
i have see bicycle books on amazon.com
just the history of bicycles
a collector might buy it , as a bike to ride arond on it is not for the average person
the parst might be worth alot of money , but i would never pay the price
