Have you used them on vintage flat edged rims? Any issues/more of less than any other 27" tires?
In fact, I have. But on the advice of my LBS mechanic, I kept them at a mushy 60psi and found them unsatisfying. He explained the risk of blowing the tire off the rim was significant if I went much higher than that. It did seem like a fairly loose fit; a little too easy to get on and off the rim. On modern hooked rims I run them them at a nice and stiff 90-95psi with no problems yet.
