Hi all,
Just to confirm (as previously stated) that a full size 16 inch spare wheel fits easily into the spare wheel well. Fit the wheel "upside down" and the screwed retainer (bought with the wheel) holds it firmly down. We didn't need to provide any support above the wheel as the existing hinged section of the boot floor spans easily across. There is also room to store things within the concave section of the wheel itself.
I didn't realise but there was an exiting jack, together with a bag containing wheel brace, tow hitch and jack handle packed in with the jack at the rear (bumper end) of the boot. Presumably all original Honda. So, check yours before buying a complete spare wheel kit with all the tools.
Cheeers,
