It'd help if you stated exactly what size of M Parallel wheels you got! if OEM and the same setup off a car as what was fitted at factory? then there's alot of threads discussing 18 inch tyre sizes - do a search.
However, the set you have, maybe someone swapped the wider rears for a square setup? so could be 8.5 inch all around or could be the fronts were swapped for 9.5 inch so you have 9.5 all around?
You might have aftermarket replica's, maybe again in 18 inch and either staggered or a square setup.
You might have the 19 inch replicas?!
Post more information as currently it's a bit too vague to help! or have a search as this question has been asked and answered hundreds of times already !
