ok, so i've FOUND a 5x114.3 wheel that's only 3.5" wide and made of aluminium - woohoo!

should fit right on to the honda, bit expensive but that's not the issue, i can't find any suitable tire to fit this. Only things i can find that are narrow enough are temporary use only
looked at i3 tyres but these are only 19" or 20". Also researched adapters to fit some i3 wheels but the increased height of the narrow tyre wont' fit in the arches..
