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.

According to the manufacturer the width is indeed 18. Google is your friend.

Personally, Sheldon's chart notwithstanding, if I wanted to try a 28 on that
rim I would try to find a way to test it before investing money in the
tires. The heavier the rider, the more hesitant I'd be. Otherwise I'd go
with a 32. On a hybrid it's not going to make much of a difference in
performance -- picking a lightweight high-pressure tire with little tread
pattern matters more -- since the rims are already fairly hefty.

I used to run 28c Michelins on those rims--no problems whatsoever.

Bloody indestructable rim btw--I put something like 20K miles on mine and
trued them four times.
