Offset or back space determines the track width. our Vibes have regular offset, many VW have high offset. If you happen to get high offset wheels and put them on your Vibe the track will be narrower. you can get spacers to make up for it, but they are an added cost, and principally, I don't like the idea.
I am not sure what our offset is.
This website is helpful. It has a video on how to measure backspacing:

If you search around you will find similar reference charts. This one i.e.:
