18" wheels...Tyre pressures?

[Jeffers]

As some of you may recall I changed my 19" rims for 18"s.
However I would like to know what the correct tyre pressures should be.
My "wonderful" Peugeot dealer said to run them at the same pressures as
the 19" rims which I believe are displayed on A pillar. I have my doubts.
The car is a TDi so it may well be different from the petrol versions.
Can any one give me an answer on this, please?

Tyre pressure is the same for all engines and rims, as stated in the pillar.

Just what I needed to know....Thank you, sir.
