There is an excellent discussion right here at NICO:
http://www.nicoclub.com/tech/wheel-tech.shtml. If you have more questions after that, please ask and I will answer.
Also, the exact values of your car wheel dimensions are in the Owner Manual for your year ... or you can take a look at the Basic Spec sticky thread at the top of this forum.
