Tires don't have to be inflated to Max. Your E rated tires will carry the same load at 65 psi as the D tires.

Thanks for your reply, but if you noticed in my OP, I said "I understand that the new E-rated tires would carry same load as Ds at 65 psi."

I want to maintain stiff sidewalls, due to hard scrubbing in tight backing. This is every time I return home, and sometimes when camping. Also, a heavier E rated tire, will run hotter at 65 psi, compared to running 75-80 psi.
