tire pressure light is on?

Get it checked by a Nissan specialist if the light doesn't go out by itself. A Nissan technician could diagnose the problem or reset the system using his scanner. If you want to find a specialist, here's a directory link for you: https://repairpal.com/nissan-repair-in-lake-city-florida

Scan the TPMS or tie pressure monitoring system, you may have a bad tire sensor, which is common. Your sure that the pressures are exactly to spec and that you do not have a slow leak, yes?
