Hello People! I just purchased an antique Schwin bicycle from somebody I know. It’s tires are dry-rotted so I checked out the measurment which is 20 X 1.75. I went to Wal-Mart and got some 20 X 1.75 tires. They do not fit! It seems that the Schwin tires are almost 1 inch in diameter larger! Do I have to get Schwin tires? Does Schwin make their tires like that so you have to buy theirs? Is their any other way to go with this?
Yes, most Chicago Schwinn juvie bikes took odd ball tire sizes. Try here.
