No, I don't actually use a 195/55 tire. I am using a 180/65 tire.
I wrestled over the math on tire sizes and they never worked out quite right. Someone mentioned measuring rolling circumference. When I did that, the numbers checked out. My rolling circumference was about 1" less than the math. It's going to depend on the actual size of the tire regardless of the numbers, and the air pressure and bikes weight.

, I rode it side by side with another f6b yesterday, and my numbers are the same, so no change from stock, all good, happy with it.
