Recommended by manufacturer 33 psi. What do you keep it at in summer and winter?

 

33 year around as recommended by manufacturer.

 

I kept front at 36 and rear at 35 on my '00 SE, '04 SL and '09 Premium, but am now running with '34 all around on my '16 Platinum. I will be monitoring tread depth across the tread at three month intervals, and if I find the tread near the sidewalls is wearing faster than the tread in the center of the tire, I will add a pound or two. But if the wear is greater in the center of the tread, I will drop back to 33.

This is the time of year when temperatures can drop sharply, and that results in the psi also dropping, as cold air takes up less space. For those of us carrying nitrogen in our tires, this pressure drop is not as pronounced.

 

Here is what my dealer delivered my new 16 White Platinum with

 

My dealer did that with my 2013 Altima too. They pump them up to 50psi for shipping and the dealer is supposed to take them back down to 33 during the dealer prep but sometimes they forget.

 

Actually had the same thing when I checked to see why my new car was riding so hard.

 

I don't kow the reason but they come off the car Carrier with high Tire pressure.
It could very well be because most new cars sit on lot for several weeks before being sold. Yes the dealer is supposed to bring the pressure down but they don't. So first thing next morning I bring all tires into spec.

 

They are shipped with higher pressure to minimize flat spotting.

 

Same here. As soon as I left the dealer lot for the drive home with my new Maxima, I knew immediately that the tires were overfilled, as I felt every grain of sand through the steering wheel and the seat. Checked the TPMS and both fronts were at 49 and both rears were at 48.

I lowered them to 40, then after the car had sat overnight, I dropped the psi to 37 front and 35 rear. Since this 2016 is lighter than the 7th gen and the tires are the same size, I may eventually go with 36 front and 34 rear.

I will go with whatever psi gives me even wear across the face of the tread. If I did mostly straightline or freeway driving, I think 33 psi (Nissan recommended) would be best. But I am turning around corners every where I go, and I am not dawdleing.

 

The pressure on tires are 47 out of factory not dealers because the automatic tire pressure control is by sounding the car horn and it is sounding at 47, I tried today on one tire and the horn sounds repeatedly until you stop pumping. So it is confusing why it allows up to 47 while factory recommendation is 33. I will check with Nissan service but I'm sure they will not have any answer.

 

a dealer i go to says, "we pump them to 40 psi after service, because most neglect checking them." that pisses me off a bit because the service details states "tire pressure to recommended."
