I was looking for tire diameters for various brands to help with setting the ride heights on my bikes. I did find some info Dan Kyle posted on another board, but it didn't include all the sizes I was using, so I took some measurements of the tires I had in my garage and made this list. Someone else might be looking for this info and may find it useful.
Make, model, size, rim width, diameter (all at 32psi)
Bridgestone BT019 120/65/17 3.5 591mm
Bridgestone BT012 180/55/17 5.5 624mm
Dunlop D208GP 120/70/17 3.5 599mm
Dunlop D208GP 180/55/17 5.5 643mm
Michelin S2 120/70/17 3.5 605mm
Michelin M2 180/55/17 5.5 633mm
Pirelli SuperCorsa 120/70/17 3.5 600mm
Pirelli SuperCorsa 180/55/17 5.5 642mm
Pirelli Diablo Corsa 120/70/17 610mm
Pirelli Diablo Corsa 180/50/17 645mm
Not only was the ride height affected, but I noticed the gearing change. Switching to Pirelli's is like loosing a tooth on the rear.
Hope this helps someone else out.
