996 with 19" wheels and tyre pressures

[Cpt Stirling]

Can anyone help or point me in the right direction please? I've just bought a 2001 996 C4. It has non std 19" sport design wheels with Pirelli 235/35/19s at the front and 295/35/19s at the rear. Any advice on the correct pressures would be appreciated.
Thanks

Sorry, yes, my mistake they are 30 profile on the rear.

Thanks Jonathan, yes, I do plan to change to the 18s. I see you are in W.Sussex, the car came from Chi, have you any experience of Auto Technics who have serviced it. I was thinking of continuing to us them as there is nothing similar on the Isle of Wight.

Thank you for the advice J and Windy, trial and error methinks (within reason). Incidentally I've just taken the wheels off and the fronts are wearing unevenly so I will will book it it for an alignment check. I'm over on the mainland for the Revival so have booked it in at an Indi in Chi and I'm sure they will advise as well. This Porsche thing is obsessive!
