See a few posts up ^^ (#43).
The thing that has not been satisfactorily explained is the *spacing* of the dimples. They look much like what would be expected if air pressure forced the inner tube through rim holes, but the spacing is wrong. Also not explained is why this same spacing occurs if the cause is "stretching" of the tube into a larger cross-section tire... random hole spacing would seem more likely.
