My last 700c wheel build was around Condor Touring rims.  https://www.condorcycles.com/products/condor-touring-rim?_gl=1%2Awmti27%2A_up%2AMQ..&gbraid=0AAAAABfW1l0KH596sESkjxn6VP09C4tM1&gclid=CjwKCAjw8rW2BhAgEiwAoRO5rI1wjQiH_J4KhYUNVUNhzJyLOQSvL96ST0If00BdSFY2ZgKq4v64IRoCw48QAvD_BwE&gclsrc=aw.ds&variant=40753356682

Photo coming up, but I’ve tried three different tyres, of different widths, and all sit wrong when mounted – about one-sixth of the tyre sits inwards by 2-3mm. The lumpy ride is really noticeable on smooth tarmac.  I’ve tried fatter tubes. I haven’t yet tried different rim tape. 

The rim width is 19mm, so 28s should be OK on the Sheldon Brown table of wisdom.  

Interestingly, I had to get to get the ERD from Condor, and the spokes turned out to be on the long side.

I am beginning to wonder if the rim diameter is 2-3 mm off? Or can anyone else suggest what is wrong?

Three metallic clangs were heard as I got past 70 psi.

Thanks. Do you think the 1

Thanks. Do you think the 1/6th of the circumference area that is “in” is the problem, or the 5/6ths that are “out”?

The problem area is around 4

The problem area is around 10 o’clock / top left on this inverted picture, pretty much next to the Condor decal.  As I say, it makes for a very lumpy ride. I’ve got some 700 x30 tyres lying around, but I’m not sure they’d clear the SKS mudguards.
