Tires on all cars are purposely overinflated from the factory for a couple of reasons. The dealers are paid to adjust the inflation pressure by Nissan when the car is delivered (dealers are independently owned and operated). It is part of their predelivery inspection (PDI). Most dealers don't do it. They just take the money Nissan pays them for the work and run......
I have never taken delivery of a Nissan or Infiniti that had the tires properly inflated.
