so does anyone know the correct reason/reasons for drilling rims?


Drilling rims only works with the outer wall of double-skinned rims,
surely? If the tube could bulge out through drilled holes it would
puncture more easily on the edges of the holes and would actually make
snakebites more common as the air would bulge out of the holes instead
of stopping the tyre hitting the rim in the first place.

My money is still on weight reduction.
