Hi Paul,
mine does not do tyre pressures. And I guess "whale mouth" describes mine accurately!
I keep mentioning my C5 because many of the bits are probably common. My C5 did do tyre pressures, and if I ran the car at recommended tyre pressures, it would yell at me from time to time. The local dealer's solution? Over-inflate the tyres...
(If you want to do a search on the Citroen pages, you'll discover my tale of woe, but have a few stiff ones first. Horrific stuff!)
Cheers,
Michael P
