1. While 28 mm tires will fit, the setup would not be aero.
2. My GP5K nominally 25 mm tires actually measure 27 mm wide when mounted on my CF wheels having an internal width of 19 mm and sit flush with the 27 mm external width of those wheels. Better, but still not optimal aero.
3. Optimal aero supposedly has the wheel slightly wider than the tire, i.e., 105% rule. As the review says, good results were obtained with 23 mm tires.
