The tire manufacturers recommend side wall pressure for trailer tires. Remember the Ford Explorer and Firestone tire thing. Ford told people to reduce the pressure to get a better ride. That worked well for them, didn't it? Some survived some didn't.
Tire pressure should never be used as part of the suspension, that up to the actual suspension system. Keeping the pressure high ensures that sidewalls are stiff enough to keep the sidewalls from flexing. Flexing side walls result in heat build up in the tire casing and causing blow outs or fires.
I have load "C" tires with a side wall pressure of 50 psi. Right now I have close to 30,000 miles on those tires, without any problems.
Do what you want but you takes your chances.
