How many bananas ya got?

As long as the tire's got a round cross section--it should ride like
any other cheap gumwall tire. They mainly come in grey--so
theoretically might be a little slippery in the rain, but I rode such
tires growing up in the rain all the time. It's not like you're doing
Xtreme cornering coming back from the ICA grocery.

What landotter said. My experience with wheelchair tires is that they
differ from bicycle tires only in their tread rubber, which is non-
marking.

That's a very strange size for a tire. The closest common size is
American 24", or ISO 507. 507mm = 20" minus 1mm, so it's easy to see
that the original intention was to fit a 20" rim with a 2" tall tire
to yield a total diameter of 24". Pretty straightforward, really.

501mm is very close to 19-3/4" inches. To stand up to its nominal 22
inch height, the tires have to be about 29mm tall, or 1-1/8". That's
a pretty narrow tire for such a small wheel-- which might be why the
stock tires on your bike are bigger. Anyway, it seems to me that if
you wanted to switch to 32-507 rims and tires (24 x 1.25"), you
probably could do so. And depending on the brakes and tire clearance,
a 24 x 1.5" tire might fit too.
