I also switched to the metal valve stems as recommended by tire dealer. However, I still only inflate to the maximum 65 psi specified by the wheel/rim manufacturer. The wheels are the 5 bolt aluminum ones seen on late model Flagstaff/Rockwood Ultralites.
I am uniformed/uneducated as to what happens if the maximum PSI of a wheel is exceeded. I just prefer to keep the PSI within specs knowing that even at 65psi (and "D" tires) I have more load capacity than previously and likely more than the trailer/axles are rated to carry.
You may want to check the max PSI for your wheels.
