C4 Tyre Pressure label missing

Hi.

First post - be gentle...

I've had a search around the forum and can't see the required info.

I've recently purchased a 16 plate C4 Blue HDI 1.6 diesel. This morning it warned me that the front left tyre pressure was low, but there is no label showing the tyre pressures and nothing in the manual either.

I've Googled, but get conflicting info from lots of different sites. The tyres are 205/55 R16 V91.

Can anyone confirm the correct tyre pressures for me?

TIA.
Brian.
