unused stud holes, don't worry about them. btw, you wont be able to
have studs inserted if you have driven on them unstudded, well at
least that's what the tire guy told me.

The dumb question?  Are tires that are molded (drilled?) for studs more
prone to flatting out?  Maybe by getting rocks into the holes where
studs
would go?  Or can you just ignore the stud holes?  I think I have
seen tires
that have the option to be studded or not...pay extra to have the studs
installed..

   Just curious, since I had a flat for no reason I can see on one of
these
pretty good tires today... Plus a flat on my wheelbarrow and another
on my
bicycle...my day for flats..
