So pictures are of door label and OEM tyres fitted. The fitted tyres are not listed on the label (no 92W on the label, and 2 psi different pressures for 92V and 92Y speed ratings for the label). What pressures should be used?

Should have asked the dealer when you asked about the spare tyre.
I never religiously follow the book when it come to tyre pressures. They're guidelines which I adapt to dependent on the conditions or driving style.

I did. They basically also couldn't explain why they'd been set so low. (33F/30R!)

Maybe I should ask another dealer!

What size tyre? The label for my 235/40/18 tyres says 41psi which rattles out my fillings. I use 36-37psi all round which feels perfect.

225/40R18 as per pic in my OP. Feel ok to me at 39F/36R as per label. Presumably label is the pressure that results in least uneven wear from the pressure perspective?

Leave as it is then.
