Check drivers side door pillar for recommended tyre pressure. That pressure is to be maintained on your car of regardless of tyre size.
You should always keep tire pressure as recommended by the OEM, irrespective of summer winters myths, etc. Recommended TP is mentioned clearly on a placard, affixed on driver's side door pillar.
