Last year ISO released some draft standards for tire sizes. It contains some handy information if you are thinking about potential tire swaps or diameter/gearing changes. Here's a table extracted with our wheel size range.
Also, across in the http://www.modernbuddy.com forum I came across some interesting comparisons.

Re: Metric Tire Size Data
Thanks Clivester - good info!
This will wind up in the Wiki by next week. I've keyed the data into Excel to add a circumference column (for easy digital speedometer cal - a roll out measurement can be more accurate), and created an English units version.
