So, no suggestions as to replacement tires for Schwinn 20 (twenty, two-zero) inch wheels? . . . NOT 26 (not twenty-six, not 26"). I hate to scrap this bike, but my daughter will only be riding it for a couple of years until she outgrows it. What about cheap replacement wheels that might be compatible? Yeah, I know, depends a lot on things you, reader, cannot see. Just looking for ideas. I hate to scrap this bike, but needs must etc.
