1949 New World with Schwinn S-8 Rims

[Oilit]

Just found a old racing bike (non schwinn) but it had schwinn s-10’s on it. Never saw one in person. Any idea if I can use any 27” tire on them? Thanks View attachment 1526694

My only other source besides the catalog is Sheldon Brown's webpage, but he says that all 27" tires are the same except "27 five" (for mountain bikes) and 27 x 1-1/2, an old Danish size. Thank goodness somebody's still keeping his old website going!

Tire Sizing Systems

Several different systems of size markings for bicycle tires are in existence. The modern ISO system is not as familiar as it should be, this article explains it.

Just out of curiosity, what kind of hubs came with the rims?

Ok. Thanks. The front hub is a prewar Airlite hub made by the British hub company.

On second thought, I just checked and there are tubular 27 inch tires. I don't think the S-10 would be for tubular tires, but I don't know for sure. What little I've read, the tubular tires are used on high end racing bikes so I'd go by what's on the rims now. If they've got clincher tires, then you should be good.

The S-8 and S-10 were for clincher/wired tires. There was also a S-12 that was for tubular tires. The S-10 fits standard 27" or 630mm tires, but they do not have a hooked bead, so likely require wire-bead tires (not foldable ones that are more common today).

That makes sense. Thanks!
