A few charts you may find useful for tire and rim sizes.
I got a lead on this Avon chart from Bikernet - my thanks to them for posting it, so I could go hunt down the info for this FAQ. My sincere thanks go to "groovesdown" at Chopper Underground for pointing me to it on Bikernet.

Here's a similar chart I took from the Maxxis Tires web site (Used to be Cheng Shin). I have used the Cheng Shin "Hi-Max" for my Viragos for years, but they're getting harder to find these days. Maxxis doesn't list them at all anymore. These are all REAR tire sizes by product name.
