The visible part of a car wheel. These parts are often highly customized by people who want to show off their car. They can be various colors. The most common colors are usually gold or silver. Some of these have special spinners in them so they spin even when the car is not in motion. Rims are one feature that set a car apart from being a stock model. Like jewelry for a car. Many people desire rims and will go to great lengths to acquire them. Some people may steal them off cars, car jack a person to get them, or kill somebody over them. They are often used as a status symbol.
The outer part of a wheel that supports a tire. The urban definition of rim would be the entire wheel. Obviously some people were very unknowledgable to cars and now rim means wheel, how gay.
"I bent the rim on my bike, good thing I don't have to buy and entire wheel."
the same morons that call nitrous (nitrous oxide) Noss, call Wheels Rims.
They are easily identified by thier "whip" which has zero performance improvements, is covered in racing stickers, has a spoiler on the trunk, and an oversized coffee can muffler; which would have added performance... if they had done a basictune-up first.
