It's worth a bit more if the chrome is good.
Some of those early tire sizes are kinda hard to find. Not impossible but they'll be $50 a pair off ebay instead of $20 a pair at the hardwware store.
AsI recall (check me on this) modern bikes have a decimal size, like 24x1.75 or 24x1.5. Those are evrywhere cheap. Fractional sizes like 24x1 3/4 or 24x1 1/2 are special order. Schwinn sizes like s-2 0r s-7 are also special order.
