Because hysteresis is definitely real-- I changed the wheels on my wife's bike without her knowledge, from 15c to 19c; the 700x25 tires were unchanged, but went from 24mm mounted to 27.5mm mounted. She noticed the difference almost immediately. We were going down a typically SoCal chunk of cracked and heaved road and she said, "
