Sounds like Pug wheels, the centre bore will probably be larger too..... not a show stopper, but will need spiggot rings if you want them located properly.
Also with that offset they will be sittig out further than normal, can look really good or just be hassle with arch rubbing depending how you deal with it.
whats spiggot rings? been told there ford wheels so should be fine, there only 15'' so should be good with arches
