Tire geometry
When referring to the purely geometrical data, a shortened form of the full notation is used. To take a common example, 195/55R16 would mean that the nominal width of the tire is approximately 195 mm at the widest point, the height of the side-wall of the tire is 55% of the width (107 mm in this example) and that the tire fits 16-inch-diameter (410 mm) wheels. The code gives a direct calculation of the theoretical diameter of the tire. For a size shown as "T/A_W" use (2×T×A/100) + (W×25.4) for a result in millimeters or (T*A/1270)+ W for a result in inches. Take the common example used above; (2×195×55/100)+(16×25.4) = 621 mm or (195×55/1270)+16 = 24.44 inches.
------
Using the above info with excel we discover the difference is only 7.4mm for the rear and 1.4mm for the front. Check out the attached image. Not sure you would feel the extra 9mm depth in the profile (96mm vrs 105mm) either.
Your right, they're so near its not worth mentioning.

| My method was not so complicated,I went to Google tire calculation dia. Suzuki front wheel dia.=21.61" Swing =21.56" Suzuki rear=21.56" Swing=21.27". Very close for rims that are 1+ smaller. |

| Mostly it helps the B650 riders feel superior to us Swingers!
The only advantage that I think they really have is checking the air pressure - the bigger rim has to make it easier. |
