At 49.5psi it measures 42mm. The front tire is measuring about .5mm less than the rear but I would think that's not an issue. Small variables in mounting maybe. They seem well fitted though. Even, all around the tire... and they do say they're handmade. I'm guessing total weight for me and the bike is around 230-240lbs. By the feel of the tires I'm thinking 47-48psi in the rear and 45-46psi in the front.
I would still like to know what the minimum is for the tire. I'll email Continental this week and see if they respond back to me.
