You've already been given the answer, can you not read?

OE Nissan wheels = conical seat lug nuts.

Mag style lug nuts are used on wheels without a tapered hole, as clearly shown in the diagram. Your wheels do not have a tapered hole. Can you not look at your wheels and figure that out?

And why would you think a dealer would fit old stock wheels on a new car? Clearly the owner put them on at some point.
