Er, not sure. They're marked 622x18 - Alexrims DH19, so
I was assuming that the "18" was the rim width. I don't
know what hook beaded means, though...

Ah, I think I know. AIUI it's a redundant leftover from the
old French style of describing the width of the tyre - "a",
"b" and "c" were standard sizes. Don't know why its still
used, since all metric tyres seem to be a "c", these days
and the width is quoted anyway.

I suppose you can see something like "700x28c" and know
immediately that someone is describing a tyre, just by the
"c" being there.

That's a good point, I suppose some manufacturers skimp on the
width for reasons of cost and weight. This might be a job
for the LBS, since if they don't fit properly I won't be wasting
money. I was planning to buy the tyres online as my LBS is
good but very small, and they don't have much of a range of stock.

Cheers,
