On my 24" Sears Spyder I have a 24x1-3/8" tire. I'm looking for a replacement, and on E-bay there is a NOS tire that also has ..."x1-1/4" added at the end, and it says it will only fit a Scwhinn S-5 rim. Now, I've seen Schwinn 24x1-3/4 tires for an S-7 rim, but I've never seen that third size addition.
What do I need?
