I am sure that it is probably true for many of you that you gain speed when you put on skinnier tires. But oddly, it did not seem to make a difference for me....
I am curious, did you try to go faster, meaning did you ride you bike with both sets of tires, each time trying to go as fast as you could (i.e. sort of like a personal time trial)? Does your route have hills, where rotating weight will make a difference? I notice a huge difference in speed when I ride my touring tires (32c) vs racing slicks (23c), but I imagine if you are out riding to ride, you may just notice that it was easier to push the lighter tire, and rather than taking advantage of that to go fast, kept at your usual comfortable pace.
