Thanks Rod, that's kinda what I'd guessed the case would be. I presume it will be ok to do the same with modern 500a tyres, as you say they'll not be particularly high pressure and what pressure there is will be enough to hold it to the rim. - Found some rather nice whitewall michlins but a nos set of white wolbers same as the originals would be even nicer...
