To all the handling nuts, remember to compare apples to apples, same width tires to same width and quality. High quality tires don't have to be rubber bands to have stiff sidewalls. You never ever ever ever see any rubber band tires on true race cars (ie formula one, GT, etc. . . and I'm not talking about drag slicks).
Rule of thumb (as posted above), the smallest diameter that clears the brakes. Note that all super/performance cars have big wheels, but also note that they barely clear the brakes. Ugly? Yes! Functional? Hell yes! Big wheels (larger than needed to clear the brakes) is PURELY cosmetic.

However, if you're tracking, you don't want a wheel so small that it limits your speed in areas of track to a speed that you could normally pass. This is hardly a fact worth considering unless you're driving a 6 second drag car, or want bragging rights of top speed (which is stupid and useless), as a 16" wheel will still allow the average car to reach into the 100s.
