noglider just rounded to 27, which would be a be a 700x32.
Now I changed out my wheelset from a 27" to a 700c. Has your bike been changed to 700c? That will allow for a slightly wider/taller tire. I changed out mine primarily for fenders. I forgot about that in my sample calculation.
The bike still has 27" wheels, but it has enough room for fenders, which I do want to add, so I'll probably just stick with the wheels I've got.
