PSI is static. if you had a 15" wheel or a 26", you would still use the sticker in your door as the recommended value.
Ideally... Use the door value. Rub a 1" line of chalk across the entire thread from inside to outside. Drive in a straightline, do not turn for about 10 car lengths. Look at chalk line. Where is it worn more? Inside? deflate 1-2psi. Outside? Inflate 1-2psi. Test again.
