Pat: Never use Mr. Tuffys, or for that matter the Park tire boots, with a
superlight tube. The problem you experienced will happen much more rapidly
with a thinner tube than with a thick one (I guess that should be pretty
obvious...). Anybody who claims this doesn't happen has been leading quite
the charmed life!
I'm sure Jobst can give us the details, but obviously there's a certain
amount of movement/friction that occurs between the tire and tube. I've
never found talc necessary for a normal installation, but suspect it might
help if you have a Mr. Tuffy installed.
