987 rims on a 986?

[Perfectlap]

The OP is from Utah which really made me take notice. If he were from NY, CA, Miami or something I wouldn't be so surprised because "rim" seems to be the norm there and not the exception. This use of the word rim is not generational either because I've heard many guys well into their 30's use the term as well as high school teenagers at my local Pep boys. The only explanation I can come up with is that at some point as rap music was growing in the late 80's and the rim became permanent. I'm just fascinated that the term hasn't gone away since you never hear sports car or racing experts, which presumably is how an auto enthusiast most often hears about the topic, on TV or print ever use anything other than the word wheel.
