although the OP's question was not about punctures, this is interesting to me....
it does not seem to make sense... a thicker tube is going to be harder to penetrate than a thin tube....
water from a roof and glass or thorns on a road/trail are not a suitable analogy.
this having been said, i would agree that a kevlar belted tire would be a first line of defense if punctures were the issue.
First line of defense - Exactly! The idea is to keep the thorns (and slivers of glass)
out, not to try to deal them after they get
in.
Now, assuming there are
no holes in the tube, I would agree with the others who believe that thicker butyl rubber tubes allow air to migrate through more slowly so you won't pump as often.
