I discovered the following link which allows you to compare your existing wheels and tires set-up to whatever new set-up you are contemplating. It provides the calculations for the differences in wheel-well space, speedometer error, etc.

Yes, this is the best site I found (and used) when determining my new wheel offsets and tire sizes since it takes both into account.

If any additional info is needed on wheel fitment and spacing/offset, take a look at the link below. Quite comprehensive, but easy to understand and great general knowledge.
