I'm not wanting to start a tire debate either, but we have had issues getting the bead set correctly when we install a 700x28 Panaracer RIBMO tire on our regular rims, and that tire seems a bit more finicky when installed on a Spinergy rim. I'm wonder if we are getting away with a slight bit of over-inflation on our regular rim, but can't do that on the Spinergy rim. In any case I don't see us moving out of the 700x28 realm but just wondered what others were using on their Spinergys.
