    I run 38psi all round on 18's and i get even tyre war across the width. You will find it rolls better as well.

    I was told by my wheel supplier to add 2 psi per size up, against what your petrol flap advises for your oem sized wheels

    Isn't that for a 3door though? The OP says his is a Sportback, and the tyre pressures for my SB are different to your image.

    Mine are something like 35/30 normal load up to 100kph or 38 all round for max load

    Its only a ball park figure because strictly speaking the pressures are different for different makes of tire. I always run light but 38 all round works well with F1's
