As someone who has lived in Saskatchewan all his life, I can tell you 
that "square tire" does not usually involve destruction of the tire.  If 
your tire is slightly flat, it can certainly freeze with a flat side. 
This makes driving interesting for a while, but the tire will thaw as it 
is driven on.
