I got the full size spare tyre on place. Besides the rim and tyre I needed to order following items:
84550-T5S-T30 Box assy, cargo floor
83850-SD2-000 Plate, anchor bolt
83853-SA7-980 Bolt, anchor, 79 mm
89211-S05-003 Wrench, wheel
Jack I'm trying to find used, because it was rather expensive from Honda.
Maybe the foam tool holder is made for markets where standard tyre is 175, because it was slightly too high in order to get floor fitting nicely. Fortunately there was three separate pads behind the foam, which were easy to tear away.
Original front towing eye is also longer than the place for it. I need to have a look if the shorter part would be sufficient and if so, shorten it.
Edit: I forgot to mention, that I bought a Dunlop all-season tyre for the spare. Something better than summer tyre if it's needed in winter and no defined direction of rotation.
