the wheel, in and of itself, does nothing to the overall circumference of the
tire. it's the TIRE which you must select, size and diameter, which determines
the tracking distance per mile and how the spedo calibrates. use this java

So I think I understand this issue but it leads me to an even bigger question...
What's the advantage of going to a larger wheel setup. I always thought that a larger setup would yield a smoother ride and better handling? If the circumference is the same wouldn't the ride be the same? Or is the difference in the different sidewall specs on the tires?
I'm running 215 55 16 now, so what would I notice if I went to a 45?
