I used to call the metal part the rim too, because that's what everybody else I knew called it. You had the tire and rim. Wheel was just a general term for the entire assembly. Just like anything else that sometimes does not have a tire. Then as I got more into cars I learned that wheel was the correct term.

Then you've got the transaxle, which most people still call a transmission. I do sometimes too.

My friend calls the windshield and rear window "the front windshield and back windshield".

Lots of people call a truck bed a box too.
