I'm back again. Ruffy Tuffies won't work on my old steel criterium frame....not enough clearance between tires, brakes, brake bridge. Not a matter of width; it's a problem with "height" of tire. So, 25mm it is. Now, who's got the most comfortable, grippy, good rolling "perfect" 25mm tire out there-- realizing there still exists differences between posted width and what the tire really pumps up to be. Supreme puncture resistance is not my main concern. I like flotation and, at 165lbs, pump to 95 back, 90 front.
