Is there any advantage to using a 700x19 tire vs. the more common and stock 700x23s? How about disadvantages? Anyone out there with experience on this issue? Would appreciate hearing your thoughts.

700 x 19 tires will ride a lot harsher than a 700 x 23. I changed to 700 x 20 once and road for about 50 miles and went back to 700 x23. I use the 20's on my trainer. If you do get the 19's make sure to reset your computer to reflect the smaller size.

Myth no. 1: narrower tires are faster. Wrong. Unless you are featherweight, 19mm would be too narrow for most people. Given the same tire pressure, a narrower tire in contact with the ground has to distort more to support the same rider. And that wastes energy and increases chance of a puncture. Some think that can be compensated for by having higher pressure. That brings us to Myth no. 2: the higher tire pressure, the faster. Wrong again. You need some softness in the tires to absorb road shock. That's the very reason why neumatic tires were used in the first place. Anyone bragging to you about 160+psi is bullsh*tting you, unless you are talking about the smoothest road surface.

About five years ago, I just gave up entirely on anything skinnier than a 28 (labeled 28, which is usually somewhere between 23 and 25mm). Granted that I'm a Clydesdale, but comparing my times on many rides among tires from 20 to 35, I just don't see much correlation except that the 35s, which I run at 75 psi for loaded touring, are a little slower. But MAN, are they cushy...
