I'm building a vintage commuter bike for my son. The bike had 27 inch wheels and could fit 27x1 1/8 in the rear and 27x 1 1/4 in the front.
I'm going to be installing 700c wheels and would like to find a tire that is about 30mm wide. The frame can fit a 700x32 Vittoria Hyper (this tire measures 33mm wide on a 23mm wide rim), but there is less than 1 mm of clearance at the chainstays. There is ample clearance everywhere else.
Most 700x28 tires measure less than 27mm wide, so I'm looking at 700x32 tires that run smaller than their label size.
Do any of these 700x32 tires run 2 or 3mm smaller than the label indicates? I'm looking for a tire with a blend of comfort, speed and reliable puncture resistance.

Any other suggestions?
