When the nuts are tightened pressure between the nut's cone and the conical holes in the wheel rim creates a "frictional lock" that prevents the nuts from coming loose.
Wheel studs/lug nuts.
on the rear\ in the trunk!
The lug nuts are glued to the rim prior to the race using a rubber cement type material. The material holds the the nut in place as the tire is installed but is weak enough to "break" as the nut is spun on.
With the car in park, break the lug nuts loose(only), then jack up the wheel and remove the lug nuts and rim. If the tire won't move. put a lug nut on half way and hit the backside of the tire/rim with a dead blow/ or rubber mallet. Don't hit the rim with a regular hammer, it will damage it.
Loosen the lug nuts counterclockwise. Next, jack up car at the jack points (there are covers below the rocker panels). Jack up car, unloosen all the lug nuts. Remove wheel, replace wheel. Tighten lug nuts until they are seated against the rim. Lower car. Tighten lug nuts crosswise. Next stop, have the lug nuts torqued down.

Centers the rim to the hub.
I belive on Contours they just pop off. Use a screw driver to pry it from the rim. Some cars, use the lug nuts to help hold on the wheel cover. So, before you pry. Look to see if your lug nuts are exposed.(Don't confuse this with fake molded on lug nuts) Then, see if it looks like the wheel cover is between the lug nuts and rim. If not, pry them off. If the cover looks like its held on by the lug nuts you'll have to remove them. You'll have to jack up the car to do this. Just remember to "break" loose the lug nuts before you jack up the car.
A test to see if you can mount a rim and put lug nuts on in a certain amount of time.
Jack up the jeep, place a jack stand under the axle, loosen and remove the lug nuts and pull the wheel off.
Any rim that is not a stock rim for that model of car.
If it is severely bent the side wall in that area may be damaged, but if it is just a curb hit, the tire should be fine mounted on another rim. If it is a steel rim, the tire can be taken off and the lip of the rim bent back into place and used.
