Tire sizes are given in the format:
Width(MM)/Sidewall height percentage of Width/wheel size
So...
205/40/17 has a width of 205mm and 82mm profile (40% of 205)
215/45/17 has a width of 215mm and 96.75mm profile (45% of 215)

I have noticed that the profile never appears to be what the formula says. For example my 225/40/18 have a "90mm" profile which is about 3.5" however if you look, it does not appear to be that big. I think it has to due w/ air pressure, weight of the car and the fact that the tire rounds over on the corner.
