[ExI] Larger diameter inner tube in smaller diameter wheel

[J. Stanton]

I've done this before and it works fine.  Tires don't stretch enough 
with inflation to even feel a lump.

As has been said, though, if you're trying to stuff a 559 ("26") inner 
tube all the way down into a 406 ("20") wheel, you might want to fold it 
over twice so that the extra weight is symmetrically distributed.

Note that tubes are much cheaper online than in stores.  JensonUSA 
usually has a good selection under $5.
