Over here, saying that will get you shunned. There is no such thing as rims, there slang for wheels. Rimz are for donks...
there is such a thing as a rim, it is part of what makes up the entire wheel...
take a 3 piece wheel design you have the spokes part which attaches to a rim or in a 3 piece design multiple rims...

i will agree it annoys me when people call a wheel a rim, but saying there is no such thing as a rim is off as well....
