What is the wheel size, nominal or as measured?
I ask because my daughter is currently riding a little Schwinn bike styled like a MTB; it came with 22" wheels for which tires are no longer available. But it turned out the larger size of 20" wheels (20 x 1 3/8, ISO 459) fit just fine. That probably won't work for you, but you may get lucky with some size that's still being made.
