This was a well know issue when manipulating the roll while splicing
audiotapes.
The funny thing was, 2" tapes are really strong.
We tied an old studio worktape to the trailer-hook of a friends car
when he got married. The tape unrolled flawlessly, the roll
clattered wonderfully on the cobbles, and when they turned out of
the drive-way it snagged a lamppost and brought the car to a halt
until the groom went out and cut the tape :-)
