You have to replace the wheels to accommodate the higher pressure.

This is mostly what I am asking, as my wheels are rated 2,600 lbs (no psi rating). I mentioned above, when looking for 15" similar steel wheels, the highest wt rating at E-trailer was 2,640.

Capriracer stated, "when asking wheel manufacturers, they indicated, but would not commit, that psi not really an issue."
