I have Bontrager Aeolus Pro 5s with 19.5mm inside width rims. Conti 5000 25mm measure 27.64mm at 100 psig. Conti 4000 25mm measure 27.99mm at 105 psig.

For a comparison. Conti 5000 25 mm at 115 psi 25.63 mm on 14 mm rim. This was the original wheels on my old Madone. With the Aeolus wheels I have to run 23mm.
