Was wondering if 17's off a Chrysler would fit my 2006 Chevy Impala?
You're asking a WAY too vague question. You need to do some research. Start with
your vehicle.
1.) How many lugs/studs (4, 5, etc.) ?
2.) What's the distance between the lugs/studs?
3.) Do you know what the offset is? Read this:
If you’re considering customizing your ride with new wheels, it’s good to have a basic understanding of wheel offset.

Now do the same thing for the wheels you want to put on your Impala.
There can be several outcomes, right?
1.) Wrong number of studs = they won't bolt up at all!
2.) Right number of studs, but wrong distance between the studs = they won't bolt up.
3.) Right number of studs, right distance between the studs, but the offset is wrong = causes tires to strike suspension components, or they won't even clear your brake calipers!
And yeah, there are "spacers" to "fix" some of these incompatibilities, but personally ... I wouldn't do that.
Good luck!
