I got hold of 1x28" Bike Rim from an old Dutch Bike which came from Holland.
Whilst in Maastricht a little while ago I bought a 28"x1.5 Tyre, thinking
that this would adiquately fit on my rim. But no. It really doesn’t seem to
fit at all.
I am at a complete loss as to why not. The tyre also quotes 622x40 (the metric
equivalent of 28"x1.5 ?) - but I thought it would be a 700cx35/38/40 or
something similar. Can anyone expand …

As far as understand it there are 2 measurements for tyres, the old way was to
measure the rim, the new way is to measure the outside of the tyre of a datum
tyre and then give enlargements on the diameter by the extra letters… or
something like that. Pashley sell the large, old style 28" for their unicycles.
