If the tire is measured to be 25mm on a wider rim, I would personally use the values for a 25mm tire and see how it rode. Wider rims tend to change the overall shape of the tire and how they "act" (for the better, in my opinion), so it's up to the user at that point. I found a slightly higher pressure to corner better at speed, so I'm 1-3 psi higher than recommended.
