24" s-7 schwinn tires (again)
 

almost done restoring 1961 schwinn american 24" women's bike. have ordered what I thought were 24" s-7 tires TWICE over the net and neither fit rims. The last one has a tag labeled "Sunlite 24x1-3/4 S-7" but clearly doesn't fit. The actual tire is a KENDA 47-520. Rims are clearly labeled "Schwinn tubular S-7". help. Does anyone have an KENDA or ISO number for me? Thanks

My guess would be ISO 547. I don't think ISO 540 was used on the juvenile bikes until much later.
