I want to try to emulate the feel with my 46mm PowerTap Carbon clinchers - which have a 20.8mm outer profile. Currently have 23mm tires; will 25mm tires feel like junk on there? Probably a dumb question, but havent dabbled with anything other than 23mm tires before. (Tire/wheel compatibility charts say its fine; but will it feel fine?)
You can run wider tires on narrow rims. I used to run 1.9-2.35" mountain bike tires on 17/20mm rims (inner/outer widths), typically at 18-25 psi, mtb races, no problems.
The tire will fold over at lower speeds at lower pressures, although I have no idea what the numbers would be for your set up. You lose some of that cushion advantage you get with the wider rim. Still, though, the 25mm tire is still wider than the 23mm, should be softer.
