another pointless thread, moderator, please delete:
Rim is an old-fashioned term that was used when referring to wagon wheel - thus the term "wheel rim." It means the outer-most edge of the wagon wheel where there was a steel band the surrounded the wooden spokes. The dictionary defines a rim as:
1. The usually curved or circular border or edge of an object.
2. The circular outer part of a wheel, furthest from the axle.
3. A circular metal structure around which a wheel tire is fitted.
for bicycles, there is a rim, spokes, hub, bearings and axle.
for cars, that big round metal thing that you put ur tire on can be called a rim, a wheel, or even a wheel rim. most usually they are called wheel, because in a car you can do a wheelie, but you cannot do a rimmee - so to me that pretty well settles it.
now moderator, please kindly delete this thread.
