You will find a tire label containing tire inflation pressure by tire size and

TIRE CARE
Improper or inadequate vehicle maintenance can also cause tires to wear
abnormally. Here are some of the important maintenance items:
Inflating your tires
When checking the air pressure in your tires, make sure that you
carefully attach the air pressure gauge/air hose to the tire’s valve
stem directly on top of the valve stem. If you bend the valve stem, it
may become damaged and cause an air leak.
