In many, if not most, they are way overloaded in some of those scenarios. As far as rougher ride, I've never seen it. Since going to the E tires vs the D tires my trailer actually rides better and nothing moves inside any longer. JMO/YMMV

Over or under pressure for your weight will cause improper wear of the tire. That’s the real issue with pressure rather than ride. We all know what a blow out costs us in damage to the trailer.
