I'm trying to replace the inner tube in the tire of a "Radio Flyer"
child's wagon.

I've removed the wheel from the wagon, worked the tire off one side of
the rim and removed the old inner tube.

The new inner tube is twisting when I work it into the tire. Should I
partially inflate the new inner tube first?

Yes. On a bicylce too. Enough that it straightens but doesn't
inflate. Not so much that it interferes

Do I put the valve stem through the hole in the rim before working the
rest of the inner tube into the tire?

Yes. Make an effort to work the tire in evenly on each side of the
valve, to keep the valve pointing straight to the center. This is
1000 times more important on a bicycle than on a wagon.

Once I get the inner tube into the tire, how do I get the tire back
onto the rim?

It's amazing how getting it on can be harder than getting it off.



It's that last little bit that's hard. But with experience you learn how to
handle it.




And it may be that it's harder for smaller wheels, I don't know, but
if there is stretching involved, maybe there is less stretching.



I've never done a tire that small; have done plenty of bicycle tires;
though.

OP may be able to push the seated portion down onto the rim below the bead.
This would push the unseated portion further out from the rim, giving him a
bit more wiggle room to lever the last bit over the rim.

But then he'd have to re-center the tire on the rim before inflating it to
make sure it spins true. I can't see it being that difficult.


MOST of the really small, like 6" and under, wheels I work with have
split rims. Makes getting tube type tyres on and off a BREEZE
