i think other than sizes, they are the same. i know a bunch of people who have various dirtbike rims laced to street racebikes. now there could be pitch issues and stuff like that but i dont know. as far as what they are, they are the same.
my guess would be if you can find a wm2 18", its be the same as a street bike, but possible with a different drilling depending on hub size.
