Tire Pressure for 19\'s & 20\'s?

Just installed my Venom 7R's, I was wondering what my psi should be for 19's and 20's with 275 and 335's?

29 or 30 psi

I have HREs and was thinking of going to 34 or 36 psi just to get the sidewall a bit firmer. I am concerned about potholes and other obstructions bending a rim. I dont see any harm in that.

I know the runflats require less pressure since they are much firmer than the average tire. My Porsche had Perillis and they required 36 psi in front and 42 psi in the rear. Same tires on my Viper.

Any thoughts?
