Well, they did make rim blow steering wheels for a while. If you can activate the horn on one of those, then you've apparently found the rim. We have people over from other countries frequently (currently have a Uruguayan PhD student living with us), and it has definitely made it clear just how much slang we use and how confusing it can be. While I like to speel things correctly (yes, I meant that), I've also learned that spelling ability has nothing to do with how smart someone is.....and why do we motor on down the road, ha. Google car/truck wheel, and some ads will list wheels and rims. I get really confused about where exactly the steering wheel rim is, since it is not nearly as defined as the lip of a wheel. It is no wonder someone from a Foreign Country has trouble understanding the nuances of our language as it changes and morphs, when banging on a road course can get you a shot rim, but it is not a rim shot.
