There is NO TIRE manufacturer that will state a pressure to put in the tire (other than a MAX design pressure for the tire). Go to any tire manufacturer web site and they will refer you to the car manufacturer sticker on the vehicle door. Tires are not manufactured for a specific car and therefore the tire manufacturer does NOT know the application/load the tire will be used on. Hence they refer you to the car manufacturer specified pressure usually on a sticker on the drivers door.
Yup, based on car weight and wheel.
I was just thinking if OP had XL tires and thought he can put 40 psi in there without bursting the tire lol
