If in doubt, go with 30 PSI all around. Kinda standard or close enough. Tyres can handle much more so it won't hurt them
Correct PSI should say in car manual or on a sticker, usually in driver door sill.

Yes 30 or 32 should be fine. It could also be on a sticker on the inside of the glove compartment or on the inside of the fuel filler cap.

Open the drivers door and read the tyre pressure sticker in the door shut.

Also the pressure must only be slightly off from wheel to wheel otherwise the tyre pressure moniter warning would have come on the idrive.
