My stinking HCH is only a few months old and I have already picked up a nail. Because you are not to have a doughnut in the front I put the doughnut on the rear and the rear tire on the front in place of the flat one. Then I tried to put the flat tire where the spare goes and guess what? It does not fit. It looks like it might fit on a regular Civic but on the HCH the pack is in the way.

If they mounted the pack under the rear deck then the HCH could have fold down rear seats and perhaps a full size spare option. I hate doughnuts!
