I have a 1999 Cavalier LS and one of my co-workers have 2002 Cavalier rims and tires for dirt cheap. I researched the bolt patterns and it looks like they have never been changed. The only changes I have seen are when they went from a 15in wheel to a 16in wheel. My co-worker has 18in under his Cavalier so I know 16in will not be a problem.
