Before you buy or service: The individual vehicle tyre placard and exact fitted wheel/tyre configuration remain the final authority. PCD or offset alone is not complete fitment approval.
15-inch and 16-inch tyres have different rear pressures
The NHP170G manual documents 185/60R15 at 240 kPa front and 250 kPa rear, versus 195/50R16 at 240 kPa on both axles. Check the actual tyre size and driver's-door label.
Wheel appearance or similar tire diameters do not prove which setting applies.

16-inch tire pressure inspection
For the low-profile 16-inch tire configuration, Toyota says to check tire pressure every two weeks, at minimum once a month, and before long trips.
Applies specifically to the 195/50R16 low-profile tire configuration; interval_months=1 represents Toyota’s minimum monthly check.
