How do I properly maintain the tire pressure on my Nissan X-Trail?

I just bought a new Nissan X-Trail and I want to make sure I'm properly maintaining the tire pressure. What is the recommended tire pressure for this vehicle and how often should I check it?

The recommended tire pressure for the Nissan X-Trail is 35 PSI. You should check the tire pressure at least once a month to ensure proper maintenance.

I've found that the best way to maintain the tire pressure on my Nissan X-Trail is to invest in a quality tire pressure gauge and check it every time I fill up the gas tank.
