As Kurt and Peter have already clarified, the rims are for clinchers. "Wired on" dates back to the days, 80-odd years ago, when it was necessary to distinguish them from other patterns of rims and tyres (called beaded edge), which were available without the wires which are incorporated into the edges of modern non-folding tyres, and which often make it a challenge to get modern tyres on and off rims without a struggle!
The only bike I have on the road at present with 27 inch rims (all others are 26 x 1 1/4") is my 1953 Gillott Taper Tube, on which I'm using modern Paselas.
