Not sure if your Oldsmobile wheel info is correct; I've owned both 2000 Alero and Intrigue and the 16" wheels were not interchangeable. Trying to remember if it was the offset? Unless I've misread your info, both don't measure the same.
...not sure on what’s the best / biggest / widest / maximum tires or rims will fit your car?
Write about the tires you are currently driving on.
