I have found that the best way to tell where they are rubbing and how to fix is to drive on the wheels for about a week. Check often as to make sure that tires aren't being cut by metal fender lip. most rubbing occurs when the tire is rubbing the plastic inner fender well. Unless of course you got a wheel with a lower offset then needed, then there will be some real problems. Anyways, jack the car up, and use an airsaw, die grinder, handheld hacksaw, heavy duty tin snips (you get the drift) and cut out just the section of the inner fender well that is being rubbed. You can tell by looking that it has been rubbing. If it is the metal fender lip, you may need to roll the fenders. Post back and let me know...
