I want to check my partners tyre pressures this weekend but i simply cannot find the correct information anywhere! The book contains some weird pressure units (not bar or psi) and when i phone local dealers i get a rnage of replies from 32 psi all round to 35 rear/32 front. Help! Surely someone knows!?

The car is a C30 1.6 diesel DriveE

 

Generally speaking, factory tyre pressures are too low. They are a compromise for a nice quiet ride.
Try running 38psi at each corner and see how it goes.
