Mine came with 48psi in each tire! I just lowered mine down to 32psi and it drives much better. I'm 2wd with the long trail tires though.Mine came from the dealer with 45 psi. Truck drives fine. And the tires have the right 'profile'. (The right bulge at the bottom).
I'd be afraid that if I let 10psi out they'd sag.
Though, Nissan says 35psi. Wonder why they delivered it to me with 45?
I will check again with a 2nd gauge.
