28 to 32 is negligible aero wise for most people, I don't disagree. 30 mph (or slower into the headwind for an air speed of 30 mph) will start to matter a little bit though, math doesn't lie. But saying wider tires are better as a blanket statement implies that you can run like 45c gravel tires and still have the same aero drag, which is by far not the case. https://www.hambini.com/cycling-aerodynamics-wider-tires-and-rims-examined-in-engineering-detail/ https://www.hambini.com/cycling-aerodynamics-wider-tires-and...
