I'm running the same size tires. How did you come up with that pressure. I asked the wheels guys and they said go factory recommendation still. Some people are running 38PSI.

I dont think there is an exact science to it--- since its a plus one tire size I think oem pressures are not as relative. Most of the tire and wheel guys I know that deal with plus sizes say you should take the factory pressure and add 1 psi per inch of diameter increase. But road conditions should also play a role in your decision.
I run a plus 1 psi on each of my wheels on my Porsche (21 inch set vs 20 inch factory) and I have very good roads where I live.
