There isn't any danger of the tire breaking down.  In fact, tires are more
resistant to impact at high pressure, so long as it is kept under the
maximum listed on the sidewall.  I would be wary of your traction on ice
with such high pressure, however.  The tire is riding on the center portion
of the tread at high pressure, which can affect traction and will affect
wear.
