I never understood casual riders’ obsession for wide tires (except for selected cases of riding on bad roads). I think that, statistically, professionals mostly ride 25 mm tires on normal roads, and they would prefer 23mm if they made shorter rides (as casual riders do). They may go 28+ on special roads, but they always have the entire system (tire / wheel / bike) tuned for aerodynamics and bike weight still remains around the minimum accepted. By contrast, when moving to 28-32mm tires (and sometimes wider rims), casual riders’ bikes are not tuned for aerodynamics and furthermore, the bike weight increases – thus, lower performance.

With regards to claimed better performance of the wide tires, the articles I read always mix performance, rolling resistance and supposed "necessity" of comfortable low tire pressures (like we always ride on bumpy roads). I rode over 40 thousand km with 23mm tires at 90-100 PSI, on average quality roads, and I never experienced problems. Maybe 25 mm would be a better choice if I were a pro, riding each time 2-3 times longer courser than I do. But really, I am just a casual rider and I think that trying to mimic pros’ setups would be incomplete, inadequate and would only harm my performance.
