I'm surprised that the original poster has failed to notice that since the
tyre fits the wheel OK, the 'problem' lies with the tube(s) not the wheel.
Though, there again, one can get fixed on a notion that is difficult to
dislodge by others with unblinkered views - been there done that.

The tube doesn't really fit the rim, it fits the tyre and tyre fits the
rim. Also the tube can't cause a bump (unless it's trapped under the
tyre bead) - the tyre holds its own shape and the tube just holds the
air inside the tyre.
