I got mine done for free from a friend that owns a tire shop. I did not specify the inflation pressure to him. Just took the car to him and went back by to pick it up later in the day. I did see another car in his shop he was doing because I asked him why that car was sitting on four flats because it was a new Altima with new tires. He said he was putting nitrogen in them too. I checked my psi on my tires and it is at 34-35psi. Sounds pretty normal.
