I'm interested in the actual width (measured with calipers) of 700C Michelin City tires in the larger widths. They come in 32, 25, 38, 40 and 47 mm widths. I know the 35's measure 34.5 mm on my 23 mm Araya rims. Are the others as close as marked?

I have some 28's that measure 30mm, but your rims help determine the size.
