No there were all 44psi - dealer was rather embarrassed when I told them
Sent an email to Seat customer care the other day and they have come back to confirm that tyre pressures are the same for 16" and 17" i.e. what on the inside of the fuel filler
 
I did do some adjustment to mine, they were set at some crazy figure when new which represented a fully loaded car with five adults and lots of luggage, little old me didn't represent that so I deflated to the required figure and the ride was much better. It took me like um three months to find that, I'm crap at checking tyre pressures regularly.
