Hello and welcome.
Until someone who definitively knows answers, I would suspect between 32 - 34 psi (which is around the norm for most cars). An experienced tyre fitter may also have a reference chart to rely on.
If your car has optional alloys or aftermarket wheels/tyres this figure may well be different to what standard sizes would be rated at.
Hope that helps. Glad you enjoy the forums.
This job should never be complete - the day I think I've done it all, is the day I resign.
