I was checking in the C-Max handbook & I see you have a Focus C-Max (same as me).
The presures I have on the back of the Focus C-Max hanbook are:
34 front/31 rear Normal loading up to 3 persons
35 front/41 rear Full loading with more than 3 persons.
The tyre pressure details can be found on page 284/5 of the Focus C-max handbook.
