Ha ha. Am I way off here then? Wide rims means more volume means lower psi, no? Rollers is the test for me - too low and they get all squelchy and sticky but 60psi is spot on, even a bit hard. Definitely too much for tarmac. Same with all tyres I've tried on these rims.
The rims are these btw http://www.superstarcomponents.com/en/arc22-ultrawide-wheelset.htm which I think are rebadged Kinlin xr22 (?)
Superstar state a 60psi max, are they just pulling that out their arse? seems a weird thing to say for a road rim if it's not necessary.Edit: a bit of googling suggests I should be running them higher, so maybe I've just been kidding myself...

Nope, 74kg. Tyre drop was the same as 90 or so psi on a normal rim. They are absurdly wide rims, but I've used them with gp4000s and Schwalbe one at around the same pressure.
Fwiw, I wasn't expecting free tyres and didn't push for it at all. I was returning them because I wasn't sure if it was a manufacturing fault, I certainly didn't expect a refund/replacement.
