Stiff as a rock and squirrelly.
Measure your tires you may not have what they say they are.

My 700x37 continentals look about as wide as the 700x32 Bontragers I had on my FX (which were excellent, btw), albeit definitely a lot taller. They roll about the same, though, so either the 700x32's were wide or the 700x37's are narrow for their size..
