ummm are ronal turbo's rat look ....no
look thorough wheel-whores for some ideas, probably the best site for checking out wheels, but ebay is just as good, cult wheels like ats classics and some bbs rm's can fit if you find the right ones. depends on how much you willing to pay realy.
pcd will have to be 4x100, and a decent centre bore of 59.1mm or over i think the micra needs. i guess unless your doing any arch work no more than a 6-7j wide wheel if you want them alot wider than steels. but dont hold me to this, i havnt tried wheels much wider than 5j on my car and they sat ok.
