How to determine correct tire psi

Recently got new tires and am worried about overinflation and under-inflation. The door panel says 33psi. Tires are Treadwright Guard Dogs 265/75/16 load range D. Right now they are at 35psi I believe. Should I lower it or raise it? The Jeep drives like a champ the way it is now. Looked at the tires while driving and you can easily see the sidewall flexing.

By puddle test, you mean drive through a puddle then look at the print? Sounds simple enough.
