I hate to ask, but are all these tires brand new? As they wear down, the diameter changes. Some of the manufacturers have this info on their websites, just to let you know.

BC.


I didn't do it, I swear.
And even if I did, what makes you think I would admit it to you?

Sorry I didn't state the obvious, these are for new tires.
Comparing Dan's measurements to mine on the same tire and wheel size, I was able to measure within 1mm of what he posted. I was suprised how tall the Supercorsa rear was and how short the stock BT012 was.

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.
Later!

I just put some pirelli diablos on my 636. i went with 180/55/17 and 120/60/17. I noticed the bike is higher in the rear and lower in the front. I also noticed that there is less low end acceleration. I was told that changing the tires would not cause that, but if it's the same as losing 1 tooth in the rear, wouldn't that be the result.

I noticed the same thing... plus, I rubbed a small hole in my hugger.. took days to figure out what the hell was rubbing until I found the hole and realized my new tire was indeed taller than the old 207

I just added the Diablo Corsa specs to the list just because of this, that rear tire is JUMBO sized!
